Go to the URL: http://www.prologo.at In the menu at the bottom choose "work". In the appearing animation click on the left picture (print design). Now do a "back" in the browser and you will be redirected to page without the animation. (everything fine so far). But if you choose the second (or any other) picuture (let's say brand identity) and go "back" nothing happens. using build 2001063008

confirming with win2k build 20010630 -> history

In the body of the page a 'onunload' event should redirect to the page, this isn't done at all. But when clicking on an item at the bottom, it works ... but not when leaving the page via the "back and forward" button.

this works fine in MSIE and Opera. NS4.X seems to do an endless loop.

I reproduce it on: Win98; en-US; rv:0.9.2+) Gecko/20010723 It took me some time going back and clicking on the links to reproduce it but the back button dosen't work any more after some clicks,but also the fordward button dosen't get activated at all.

Radha, any progress on this? This (back button not working) continues to be one of the most prominent 6.1 (rtm/pr1) complaints.

updating keywords

A testcase is available at http://www.world-direct.com/mozilla/backandforward/backandforward.htm It starts with "work_s.htm". Just click on the first picture. You are now on "Print Design". When you click the "back button" you are directed to "work_s2.htm" (this is done in the body - 'onunload'). Just click on the second picture now. You are on the "brand identity" and no back or forward buttons work now anymore, although this page has the same code. What is strange: just type a URL - www.mozilla.org ... then the onunload event is triggered (you are directed to "work_s2.htm") and then the mozilla website is loaded.

what's the current status of this one?

The back button is working correctly! any clues who?! :) The forward button is still deactivated. using build 2001101909

The back button does not work on http://www.iht.com/frontpage.html Build 2001102106. The malfunctioning of the back and forward buttons and the mess in the history (the Go menu) is exactly as I described them in bug 92743 , which was marked as duplicate of 88684

Nominating since lots of users are still reporting running into this.

In today's build, the back button does work after visiting the "brand identity" page. The back forward buttons respond properly. However the Go menu is filled with entries for these 2 pages. Every time back is pressed, a new session history entry is created for the redirected page and added to 'Go' menu. However, back and forward buttons are always updated and respond. NS4.x goes in a loop. I don't believe that this bug should be a 0.9.8 stopper. This is a special situation. I will see if something can or should be done about the Go menu. I don't believe this is a regression either.

OK, pulling off the 0.9.8 list.

Testing with build 2002011803 on winxp the "forward button" isn't activated at all - so not working. This testcase worked already fine in mozilla - it is a regression. If there is a chance for it to get in 0.9.8, it would be fine.

Major sites affected (bug 117259)

when you click 'back' from the Brand identity page, the forward button will not be activated, because, when the 'brand identity' page gets unloaded, its unload handler kicks in, which redirects you to the page you wanted to go through the back button. Technically you are taken one page forward. So, you may think that you went back to the previous page, (since the previous page and the forwarded page are the same), but technically you went forward to that page because of the redirection. That's why, everytime you click back from the brand identity page, a new entry is also added to session history, which is evident by the increasing number of entries for that page in the 'Go' menu. In my opinion, as long as back and forward buttons respond, there is no bug here.

markush, Can you provide some testcases regarding misbehavior in top100 sites.

Ohh yes, before the Back Button takes action, the JavaScript code drives the user to a new web page. So the 'back button' is not part of the story here. The fact that the JavaScript directs the user to a new page is cool and it's good that forward button is not activated - that's the proper behavior since time traveling is not possible.

IHT.com is in the top 100 list, AFAIK. Just visit it, and try to get back to the front page by forward and back buttons. The menu and IHT logo are an easy workaround so no real showstopper, but it is still less than beautiful.

I really do think we should address this one as soon as possible. www.iht.com (and of course others) is far too important to forget about it ...

Maybe another one (which is probably the same problem): go to informer2.comdirect.de, select 'News Informer'. select the 3rd news, then press back button...nothing happens. Press it again....you come back to the entry screen. build is 2002012921

nsbeta1+ per ADT triage team

I would like more specific steps to reproduce this bug in informer2.comdirect.de. I do not understand that "3rd news".

3rd news just means: take e.g the 3rd news out of the list, or any other except the first one

*** Bug 124373 has been marked as a duplicate of this bug. ***

I have figured what the problem is with www.iht.com, however its going to be a hard problem. Can someone provide a simple trestcase for informer2.comdirect.de. The site often refuses the connection and makes debugging tough.

Radha,dont know where your physical location is, but over here i dont have a problem accessing this site. What can i do to support your debugging?

Axel, Are you saying that you have no problem with www.iht.com? ie., you don't see 2 entries in hte go menu once you visit the site?

This patch takes care of the problem with informer2.comdirect.de. I'm still working on the problem with www.iht.com

Hello Radha, dl'd the latest builds (2002022021 for linux and 2002022103 (?) for windoze). Had a look at iht.com. Backward button not working at all, and the windows version crashed several times. Both versions did not work with informer2 -> no change to prevoius behaviour

axel.braun@gmx.de: This can't work because this patch is not checked into the tree. A patch needs a r= and SR= and after that the developer will add a "checked in" comment. (and mark this bug fixed)

Good point, Matthias, didnt know this. I'll try again when the patch is in.

I have a patch for the iht.com problem, but just visiting that site crashes the browser. S, I'm not able to verify my patch.

I'm moving this one out. This bug should be fixed once 105299 and 124427 are fixed. Both these bugs are waiting for approval and/or reviews.

This now works for me in today's build.

This bug got fixed, by fixing 105229 and 124427 last week.

Sorry to disagree, i played around a little with today's build (2002030621): Informer2.comdirect.de -> on the main screen, go to 'Kurslisten' -> Deutscher Aktien Index (DAX). -> Result: the DAX-ranking is displayed. From there, go to 'News-Informer' -> First news is displayed. Select another news from the list (e.g. the 5th one) -> 5th news is displayed. Press back button -> DAX ranking is displayed expected result: Screen with first news displayed again#

Works for me with build 2002031104 (WinNT4.0) from the 0.9.9-trunk

vrfy'd fixed using 2003.02.19 comm trunk on linux rh8.0.

This might have regressed since being fixed. See bug 251944.
