I get a 'the dcoument contains no data pop up', 1. whilst commiting a bug to bugzilla, (on pressing 'commit'), the data was actually sent and 2. when I try and log onto www.msn.co.uk and get my hotmail. When I log on to hotmail, if I click on any of the tabs, 'inbox' etc. the pop-up appears, and I can't get mail.

Reporter, I cannot confirm either of these issues. Are you using a recent build? If not, please download a recent build and verify if these are still problems for you. If they are, please feel free to reopen this bug, but please give us your build ID when you do. win32 2002040303

I've seen that recently too when sending an attachment. Reopening

Reporter, have you seen this on a recent build?

I can confirm this. Build 2002041003 under XP. I started seeing it a few days ago and it continues. Unfortunately, it seems complete random and I can't reproduce it at will. But about 5% of all links I click on (it doesn't seem to matter which ones) result in the "This document contains no data." pop-up. If I click on the link again, it works.

I confirm that I still cannot use hotmail with build 2002040608, due to this 'pop up' issue.

I stopped seeing this bug as of the 2002041103 Win32 (under XP) build. I'm now using 2002041203 and the bug is still no longer present. It appears as if code was checked in a couple of days ago that corrected the situation. FWIW: 202041103 also stopped random crashing and no warning browser terminations that I'd been seeing for several days. I've never had any issues using Hotmail. (Except for bug 114812.) Changing my "confirmation" in comment 5 to WFM as of 2002041103.

Now I'm seeing it again as of 2002041803. <sigh>

I am using 2002040608 and I can now use Hotmail properly and I don't get the pop-up anymore.

I have seen this with cvs builds going two or three weeks back, and even with yesterday's cvs. Mozilla/5.0 (X11;U;SunOS sun4u;en-US;rv:0.9.9+) Gecko/20020418 To reproduce: go to http://www.ireland.com/, and then click on "Click here for the Irish Times", at the right bottom of the News box on the left. Works every time for me (i.e. I get the "document contains no data" box). This works fine with netscape. Of course, it is possible that the cgi they're using for dynamic content is buggy ...

I can't reproduce this by visiting the URL in comment 10 (win32, Mozilla 1.0 RC1), but I am having the same problem as comment 5 - the "Document Contains No Data" error seemingly randomly popping up and the page failing to load. Perhaps we have two separate bugs here - the error popping up at random and the error popping up in response to certain pages (possibly related to Bug 140014?). Personally I don't use Hotmail so I can't check this out fully. Although this problem can be worked around by trying to load the page again, this is a pretty major bug. I never had this problem with 0.9.9 or earlier. I feel that it must be fixed before Mozilla 1.0, as it is a very real and obvious problem.

I have been seeing this when searching bugzilla with build 2002041508 on mac 9.2.2 very annoying

same error message unexpectedly appearing also reported in bug 140711, bug 139879, bug 140014

Resolving as dup of bug 137965, fix checed in on trunk April 18 (branch Apr. 25) See http://bugzilla.mozilla.org/show_bug.cgi?id=139164#c9 *** This bug has been marked as a duplicate of 137965 ***

Should I file my problem (comment 10) as a separate bug then? It is still present as of yesterday's (April 30) cvs.

Great, now this one's closed as a duplicate of bug 137965 - which was resolved fixed over 10 days ago even though the bug persists! Either this isn't really a duplicate (the description of that bug indicates a step to reproducibility even though it happens when those steps do not take place), or that bug is really not fixed. This bug is also seems to be causing problems with form submits as indicated by http://www.mozillazine.org/talkback/read.php?f=1&i=2497&t=2475. One or the other of this bug or the one it's been marked as a duplicate of needs to be reopened.

Reopening based on comment 16. Possible dup of bug 139879. I don't see this bug when using bugzilla. 2002050108, XP.

Still seeing it with 2002050108 under XP. It does not necessarily happen with Bugzilla or any particular site. It's seemingly random and happens once out of every 40 or so hyperlinks visited. (It's not repeatable that I know of. It may or may not happen with any given site, and if it does or doesn't, the behaviour could reverse itself later.)

The URL in comment 10 works for me every time, reproducably. As the problem seems to appear at random for other people, is there any kind of debugging/trace I can do here to get a handle on it? After all, this could be a compiler/optimisation error (but I haven't touched my .mozconfig since last July).

Odd, now I *CAN* get the error every time I use the link is comment 10. I could swear that I tried this after the comment was posted and it didn't generate anything. Now, it's also always reproducible for me (I tried it 5 times). The error also occurs when clicking the back arrow after finally getting to the link (after ignoring the message the first time).

changing component.

I've tried the link in comment 10, but I DON'T get the error popup. I've never had this problem. Linux 2002041711 (1.0rc1).

I reported a duplicate of this bug a while ago, and was told that the new builds had fixed it. I've tried with 20020501 and still the bug persists - although I didn't have it for 3 days. I'm getting it for 10 percent of my links at the moment. It says - "Connecting to foo.com..." then cycles very quickly back and forth between that and "Sending request to foo.com...". As soon as I notice that, I wait about 3 seconds and get the "no data" pop-up. I don't know if that helps at all - some kind of loop mucking up? Good luck - it's a terribly annoying bug.

*** This bug has been confirmed by popular vote. ***

I can confirm the activities in the previous comment, though I have no idea how to reproduce it except to submit data to bugzilla (happened to me 3 times just now while trying to vote for this bug). Using build 2002050705.

I can confirm the activities in the previous comment, though I have no idea how to reproduce it except to submit data to bugzilla (happened to me 3 times just now while trying to vote for this bug). Using build 2002050705.

Oops. Was trying to submit my comment and kept getting the 'document contains no data' window. Same activity as comment 23.

I confirm seeing the same symptoms randomly, but very frequently (1 in 5). Using RC1 and RC2 (2002051006) under Windows NT 4.

I have seen the spurious 'document contains no data' symptom in all builds (currently 2002051006 win98) and have just now found a workaround. I am connected via proxy. With Netscape 4.7x and MS-IE, I had both 'HTTP Proxy' and 'Socks Host' defined. Mozilla was configured similarly (I think it automatically picked up my Netscape settings). Netscape and IE worked fine but Mozilla was randomly failing to load links at a rate of 5-10%. If a link failed to load, I simply reclicked it and it would load on the first or second retry. The workaround (for my proxy at least) is to remove ALL proxy definitions except for 'Socks Host'. It is interesting that IE and Netscape 4.7x handle multiple proxy defs but Mozilla apparently gets confused. There are several other similar bugs reported that may be caused by conflicts over multple proxy defs . . . http://bugzilla.mozilla.org/show_bug.cgi?id=143816 http://bugzilla.mozilla.org/show_bug.cgi?id=143096 http://bugzilla.mozilla.org/show_bug.cgi?id=141451

Addendum to my previous comment: Problem persists when configured for 'HTTP Proxy' with 'SOCKS Host' cleared. Problem disappears when configured for 'SOCKS Host' only. Using SOCKS v5. Similar report: http://bugzilla.mozilla.org/show_bug.cgi?id=140711

I am not using a proxy but am still getting the error. I still believe that there are possibly two bugs - some people seem to get the error specifically when submitting forms, but others (like myself) get the error seemingly at random.

mass futuring of untargeted bugs

I also faced the same problem under Windows XP. The workaround is to disable "Enable Persistent Connections" under "HTTP Networking" tab. After disabling the option, the error seems do not happens again.

Re: comment #33, I can confirm that the problem seems to disappear when switching off "Enable keep-alive". Solaris 7/8, though, not XP ;-)

As of 2002052306 build the bug is still there. It seemingly appears at random but I often get it at http://www.google.com Site loads fine after re-entering the url. It's a very annoying bug which has not been resolved since the previous build.

lhecking, nat: are you connecting to the internet via a HTTP proxy?

nope, direct connection (no proxy, just firewall).

Seeing it on a number of sites, including the one in comment 10, on Windows ME, no proxy. Been seeing it with every build in the last few weeks. I'm getting the impression it's a Windows only bug, since no one i know on Linux gets it anymore.

I'm getting this on 1.1a for windows. Also, seeing a lot of connection refused pop ups. Neither seems to reflect any kind of real problem as the pages seem to render fine. The pop ups are very annoying however.

I get this popup almost everytime when i surf on http://www.aftonbladet.se Surf around, and you will get this error. Press the link again, and it works.

I have tried link at #40 and don't have any problems with Netscape 7.0 prerelease.

I got the popup once out of about 40 links. (It wasn't reproducible on the one link that produced it.) 2002072408 trunk, Windows XP. It's certainly not a good test site for me since it's so infrequent. Also, test case from comment 10 is (again) not producing any error for me. However, this behaviour appears and disappears so often that I put no stock in any current absense of the popup. I'm sure I'll see it again.

I'm getting this bug frequently with Mozilla 1.0 (the official stable release) on Win XP. A good site for testing is http://dict.leo.org, an English-German dictionary. Just enter a word in the "Suchbegriff" field and hit Enter to get the translation. I'm getting the "Document contains no data" pop-up in about 50% of all cases on this site. The problem does never occur in MS Internet Explorer. Joerg (jb@sunlight.de)

interesting, i'm unable to repro the problem using the 2002072708 trunk build under win2k. often, this error results from a problem with your network connection. are you using a modem or some kind of broadband?

I get this error at work, lan, and at home using broadband. Windows 98 and on Windows 2000. It does not happend all the time, only sometimes.

I would like to clarify the issue by pointing back to comments #33 and #34. At some stage a few months ago, the default preferences for http networking and direct connections changed to enable keep-alive=on. This was when the problems started on my end. Since switching off enable keep-alive, I have not seen this pop-up again.

interesting, well... we've always had keep-alive enabled. it was just previously called "persistent connections" in the preferences dialog. keep-alive is a performance feature used by all modern browsers... if we detect a situation in which the document contains no data, then we try to load the document again using a new connection. perhaps the problem is that we should wait a little while before opening the new connection. maybe the server is overloaded or something like that.

OK, I turned "Keep alive" off, and it seems to solve the problem. I tried http://dict.leo.org again (see my comment #43), and this time I got no more pop-ups although I tried a lot of requests. Nevertheless the problem should be fixed so we can use "Keep alive" again.

Just an additional data point for this bug: a site on which I frequently (but not 100% reproduceably) get the pop-up is http://www.haaretzdaily.com. It's a news site which refreshes automatically after some time-out, so if you leave the browser open to that page it should eventually get the pop-up. Using 20020530 (Mozilla 1.0) on Win2K.

*** Bug 154818 has been marked as a duplicate of this bug. ***

Ok. I have this bug very often on my Windows 2000 using many different Mozilla's builds. I recive this very often in Bugzilla. After calling a query, or while looking into a bug. I tried changing HTTP/1.1 to HTTP/1.0 and switching 'Keep alive' and 'Pipeling' - nothing changed. Every time this happens, in status bar i see fastly changing two strings: "Connecting to bugzilla.mozilla.org" "Sending request to bugzilla.mozilla.org ..." about for 2 seconds

Meaby it'll help - The same actions in IE6 (only on Bugzilla) produces blank error page. Steps how I can reproduce it: 1) Open http://bugzilla.mozilla.org 2) type "document contains no data" into text field. 3) press "Show" button 4a) In Mozilla i will recive "The document contains no data" alert 4b) In IE6 i will se an error page ("Cannot view this page")

But if i'll go to "Query" and there type same string, serach will work. I'm behind gate (whole company has one IP and gate to the net). We have two connections - both synchronize stable 4mbit. I cannot find in my memory any other page occuring this problem.(my local Bugzilla works fine) Add: At now i'm trying to send this post under Linux Mozilla 1.1 final and reciving same problem Add: Under Konqueror i recived blank page with alert "Connection with server bugzilla.mozilla.org was broken" Add: i was able (under Mozilla) to send change (dupe) in other bug. But cannot send this form with full comment.

When i splitted comment into 3 short parts it work! But it does not explain why one-line input on main bugzilla.mozilla.org page doesnt work

Zbigniew: sounds like your proxy server is at fault especially if you are observing essentially the same problem under both Mozilla, IE, and Konquerer.

i'm not using any proxy server.

oh, ic... then perhaps your router is dropping connections for some reason. basically the error dialog corresponds to a TCP/IP connection that is RESET abruptly by the other end. there are many factors that could lead to this problem, but i'm almost certain it is neither a problem w/ mozilla nor a problem with bugzilla.

Ok. Last test 1) bugzilla.mozilla.org 2) into input "document contains no data" 3) Run query. Netscape 4 - works Mozilla 1.1 - alert IE6 - error page

does netscape 4 always work?? very strange. any chance you might be able to supply a packet trace? there's a good tool available at www.ethereal.com that you could use.

I created logs for exactly this actions: 1) Open bugzilla.mozilla.org 2) Typed "document contains no data" 3) Runned query IE6 - http://alladyn.art.pl/gandalf/ie6.log.txt Mozilla 1.1 - http://alladyn.art.pl/gandalf/mozilla1.1.log.txt NS4 - http://alladyn.art.pl/gandalf/ns4.log.txt I saved it in RedHat 6.1 log libpcap (tcpdump) If it's what you were asking, i can create similar for other actions that provides to this bug (like strange difference between "open in new tab" for link, and typing link directly into location bar)

Oh. Forgot to check on Opera 6.04 - works fine.

I HAD a reproducible test case that happened every single time I clicked on a link - but as I was getting to the end of this comment it started working again. (Typical.) I'll describe the symptoms anyway. The site was http://canada411.sympatico.ca - click on Find A Person. (The actual page that links to is http://canada411.sympatico.ca/eng/person.html .) It works now, so don't bother going there to try to reproduce. In Mozilla, "The document contains no data." popped up every time. In IE, I got "The page cannot be displayed" as a message, although the title of the page was actually "Cannot find server". The IE message was obviously wrong, since the site itself *was* accessible and the other links on the server worked. Mozilla was also wrong to display what it did since it should have returned a 404 if the page didn't exist, or "Connection refused..." if the site was inaccessible. As I say, this happened every single time I tried for 10 minutes. Just as I was typing up this test case it started working again (typical). But hopefully this adds *something* to what's been happening. The site itself is accessible and the document exists (or else a 404 would have been generated) - so something else is reponsible for this. Also, as I've mentioned, it's an issue with IE as well. So I don't know if that makes this bug INVALID or not - since it turns out not to be a Mozilla-specific thing after all. However, Mozilla should be handling the overall condition for the message better than it does...

Microsoft relased SP1 to IE6 which fix a bug. In IE6 SP1 works both, my testcase and Jason's. So at now it's Mozilla problem only which should be fixed.

> In IE6 SP1 works both, my testcase and Jason's. My testcase only worked for 10 minutes - as I said in comment 62. After that time, the site worked again just fine. So it should not be considered a test case at all. In fact, my point was that this is happening randomly (except for the site I reported where it was reproducible 100% but only for that 10 minutes) and that there seems to be no way of establishing a test case because of this. (Nor can you say that because IE works at a site and Mozilla doesn't - one time - that it's a Mozilla problem. My experience showed that it's unrelated to the browser used, it's something more general going on. (Which may not necessarily mean that Mozilla shouldn't change how it handles it, but I'm just pointing out that it's not actually a Mozilla *bug* - in fact, I'd say that the Severity here should be dropped to Enhancement due to that.)

My problem (with bugzilla.mozilla.org) disappeard on IE6 after installing SP1. On Mozilla i still recive 'document contains no data'.

i do have one thing i'd like to try... currently, when we detect the "document contains no data" case (which corresponds to the server abruptly terminating the connection), we try sending the request again. we repeat this up to 10 times until the request succeeds. if it continues to fail in the same way, then we eventually give up and the user is shown the error dialog. now, i think mozilla could try waiting a little bit before retrying. this might improve the chances of getting a good connection. bbaetz: what do you think?

i saw this only on generated pages (reported a possible dupe) and the server is possible busy at that moment. >we try sending the request again. we repeat this up to 10 times is this a complete new connection or do we retrz it only in the current "keep-alive" session ?

-> moz 1.3

It's really very annoying. Today i tried to post medium length comment to bug 170272. I had to chop it to 4 parts to send it without "document contains no data" bug. I'm unable to send any post to phpbuilder's forum because of this.

of those folks who experience this bug, how many of you see similar problems with IE or NN4? this is a real network error, but i have some thoughts as to how to make moz minimize the problem. so, be careful duping other bugs against this one. this bug is only about adding a delay in our restart mechanism in the hopes that that will reduce the likelihood of this failure.

Darin. I not enought in this problem, and i cannot decide which part of my problems is caused by |my| network, which one by |site| network and which part by Mozilla. With http://bugzilla.mozilla.org i see that form on the main page works with NS4 and opera, but fails on IE6 and Mozilla (Comment #58) . When i'm trying to type long comment in bug Mozilla fails (Comment #73), IE works. When i was trying to write anything on http://phpbuilder.com Mozilla and IE failed, Opera and NS4 worked. I'm also unable to add any Attachment to bug because of this. Everytime i see about 10 tries in status bar, and alert "The document contains no data". I hope this is related wioth this bug, right?

thanks for the feedback. i was hoping you would confirm my suspicious about moz and IE behaving similarly. iirc: 4x has this kind of delay before restarting, so perhaps the solution to this bug will fix your problems as well.

I just downloaded recent build and cannot reproduce bug. Meaby it's change in my lan configuration, but meaby it's some fix in Mozilla.

After long use of this Mozilla i see that i still sometimes see this bug. For example i wanted to add new Attachment in bug 177699 and saw this.

see bug 177326 which contains a patch that might solve the real problem here.

No. it didnt solve my problem. I installed trunk Moz 2002110108 and runned http://bugzilla.mozilla.org . Typed "spam blocking" in <input> and pressed |enter|. Result: "Document contains no data".

The same actions in Netscape Navigator 4 resulted in list of matching bugs (normal work).

Still not working in build 2002101612

Still seeing this with 1.2.1 on WinXP. www.haaretzdaily.com gets TWO pop-ups for every load of the home page or any article off the home page.

this will be a lot easier to fix once bug 176919 is fixed.

futuring since bug 184122 has been fixed. this timeout is less critical now.

I still see this pop-up with 1.3b, Build ID 2003021008 Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.3b) Gecko/20030210 sample page: http://forums.2cpu.com

christian: perhaps you were hitting bug 189965??

Darin: yeah, it was this bug with entries in hosts-file.

I see the "the document contains no data" with 1.3b, but I don't see it with 1.3a. That's why I desided to use a-version. But also this version is annoying because some web-pages don't display before I press the refresh button. Sometimes they do, sometimes they don't. With IE, there is no problem. OS is win2k

I'm having the same problem at Hotmail. Build 1.3b WinXP with no proxy.

I'm seeing what I think is this bug in Mozilla 1.3b on windows XP. My connection is a 52kbps dialup through Penn State university. Symptoms: spurious "Document contains no data" popups appear at various sites. There is apparantly a degree of randomness -- often reloading helps. Some sites are affected more strongly than others. One place I see this fairly consistantly is at http://setiathome.ssl.berkeley.edu/reference/triplets.html (or pretty much any other URL at seti@home) as long as the page isn't already in the cache. This occurs ONLY if "enable keep alive" is checked in the HTTP networking preferences. It is an effective workaround for me to uncheck this option. (Thus for me steps to reproduce are make sure "enable keep alive" is checked and browse to an uncached page on the seti@home site. I see the bug about 80% of the time this way.)

Travis : 1.3b is old and your bug is known and already fixed

I use Gentoo and am fully up to date with stable. I use Mozilla 1.7.3 and I get the error to from time to time. I notice it a lot when browsing ebay.com. I use adblock, but noticed it before then, and I connect to the net through a 56K modem. There is no firewall or anything that I know of to block anything. Hoping for DSL soon. If you need more info from me, let me know. Dale

I get this using 1.8a6 on XP Pro SP2 a lot. Specially when I try to open a few pages at the same time. Various websites give me this, and I have only Norton Antivirus running. Windows Firewall is off, and I have no additional popup blockers, firewalls or proxies.

I have a simular problem. Whenever I view my home page I get the following pop- up Alert "This document contains no data". I have to click the alert off several time to remove this alert. Then when I try to view somthing on the home page {ie e-mail, stocks etc.} the pop-up alert reappears. It got so bad that I could not look at my e-mail, because it would not let me log-in. Additionally every web site I go to this alert showes up. It got so annoying and frustrating that I finally had to give up firefox and go back to IE. I was using the latest firefox download as of Sept. 05. I am using Bellsouth DSL, Trend-micro,SpySweeper, Window Washer. I even tried deleting and reloading firefox ,but still had the same results. I love firefox and would like to use it because it has some great features. Hopefully mozilla will fix this bug in the future in a later version of firefox... Please e-mail me when this problem is fixed and I will be back.........Thanks Fred
