Did you send a crash report ? http://developer.mozilla.org/En/How_to_get_a_stacktrace_for_a_bug_report

Run Firefox in safe mode: http://support.mozilla.com/en-US/kb/Safe+Mode and then try again and see if it crashes.

The safemode is part of the "get a stacktrace" instructions.

Which printer are you using ? I will try to contact someone at Canon.

bug 470981 mentions a Canon Pixma MP610

Contacted Canon USA via Web-Form

Still have same problem. Now using Firefox 3.0.5. Printer Canon IP4500 Pixma. Strawberry

The cannon support suggested that you upgrade to the latest printer driver fro their homepage : ========================================================================= 1. Visit Canon's web site at: www.canontechsupport.com 2. On the Consumer Products Home Support page, below the "Please choose the model from the dropdown menus below:", select your model in the following manner: a. From the top dropdown box, click on the down arrow and select Multifunction. b. From the middle dropdown box, click on the down arrow and select Inkjet as the product type. c. From the bottom dropdown box, click on the down arrow and select your model then click GO. 3. On the Support page for your model, click the Drivers & Downloads tab. 4. Select your operating system from the "Select OS" dropdown box. 5. Scroll down the page and you will find all downloads available for your model and the selected operating system. Click the link for the file you want to download. 6. Instructions for completing the download and installation will appear on the page that follows. You will also see a Disclaimer at the bottom. Review the disclaimer and click I Agree - Begin Download. ======================================================================== It would be nice if you try it. If you still crash I will try to get a real developer at this issue.

The driver update seems to have worked. Download the first driver listed (Mac OS X CUPS), open the print dialogue (apple-p), from the drop down printer menu, select add printer, click on the Canon MP610 series, and wait for it to load the settings. Then go to the drop down Print Using: menu and select Canon IJ Printer, click add and confirm that you want to add the same printer again. It should be fixed now (it was for me) if not, I would recommend switching which printer is default by selecting Print & Fax Preferences from the Printer selection menu in the print dialogue. Thanks a lot for all your work on this Matthias!

strawberrymaggie: Does the driver update fix it for you too?

Oh, I thought that https://bugzilla.mozilla.org/show_bug.cgi?id=348605 was the same as this one. Perhaps it is different after all. I'm using Firefox 3.0.5, OS X 10.5.6 on a Mac Pro and I'm using the MP610, too. The driver version is one on the website right now, 10.1.2.0, so the driver update does NOT fix this. In fact, I just got the printer, and this was the only driver for this printer ever installed. Here is an example of a typical crash log: http://crash-stats.mozilla.com/report/index/f0fadd81-f4f5-4d84-8569-25a912081225?p=1

I'd advise trying the other print driver then. It gave me two, I did install both although I thought that it was the CUPS one that made it work in the end. However, it is quite possible that it was the other. I'd probably submit a report to canon if you can't get it to work, since it does seem to be crashing in their drivers. Good luck.

Please ask the canon support and tell them that you have the latest driver and point them to this bug. the stack trace from comment #14 is the same crash in the driver. I will ask them again if you fail to get an answer.

Sorry, forgot to mention the other, second, driver (6.9.3) works. I'm not sure what the difference is between them other than first one crashes and the second one does not. (I'm not sure why the first driver is referenced as CUPS. If I understand correctly, all printing in OS X is managed through CUPS.)

I am using a Canon MP970 with Firefox 3.0.11 and Mac OSX 10.5.6. I have had this problem for quite some time. I was able to resolve by using the other driver on the Canon support site for this printer. Nice to have FF working again. thanks for the info.

I called canon today and gave them this bug number and some information. hopefully this report will be sent to an engineer. OK, using Frank L's printer model, I reached: http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&tabact=DownloadDetailTabAct&fcategoryid=334&modelid=15481 And in: Please select your operating system to view available drivers and software. I selected "Mac OS X" at which point, it had a table, which I'm trimming to show the relevant bits Date Posted Version/Description File Name 08/27/2008 10.1.2.0 (OS X CUPS) mp970sosxcp10120ej7.dmg 03/25/2008 6.9.3 (OS X) mp970sosxpd693ej7.dmg 11/28/2007 13.9.0 (Scanner Driver) mp970sosxsd1390ej7.dmg Frank L: I take it that you're saying the 8/27 drivers cause crashes but the 3/25 drivers work?

Yes that is correct. I was successful when I used the 6.9.3 driver. 10.1.2.0 CUPS causes FF crash after second print.

I have this same problem (FF crashes every other time I try to print) and I haven't found any solution. In the Canon website there is only one driver for my brand new mp450, dated 11/08/2007. I believe it's the same as I have now. I hope someone could fix this, it's really annoying...

Sorry for misinformation: my Canon is mp540, not mp450. There are no drivers for this one at Canon website...??

Lariza: try drivers from here for the mp540: http://software.canon-europe.com/products/0010641.asp You can narrow it by operating system (presumably OS X) and language (I think they only have English, but I don't think printer drivers would be language specific). I believe that the driver you want would be "Printer Driver for Mac OSX (7.11.0)", but if that doesn't work, you can try " CUPS Printer Driver for OSX (10.10.1.0)". I think the reason you didn't see drivers might be that I think this is a non-US printer, just so you know. If anyone else has similar problems, you can try googling canon <your printer model> driver.

Thanks for the tip! I had a little bit weird installation process: after I installed the 7.11.0, my mac couldn't find any printer anymore (a bit worrying!). Then I installed the second one (CUPS). Now it finds the printer, happily, but when I check the preferences, the driver it's using is the 7.11.0, not the CUPS one. Well, I'm happy it works now anyway, thanks for the help! :)

Duplicated with the Canon MP610 using the 10.1.2 CPS dirver. Using the IJ 6.9.3 driver seems to correct the problem.

Using the very latest drivers for my Canon iP4500. Still happens, has plagued me for months and months...crashes every other time I try to print in FF. This is consistent and reproducible. Specs: Mac Pro, 1xQuad Xeon, 10GB RAM, Leopard, FF 3.5.

Guys, PLEASE complain by phone to canon (1-800-OK-CANON). The ball is in their court, and right now all you're doing is turning this bug into a mess, which will hurt anyone's ability to read/fix it (including the engineer from Canon, who will eventually read this bug and hopefully be the one to actually research and fix their driver). If you want support from us, please use http://support.mozilla.com instead (note that all we can do is walk you through their web site to either their other printer driver or to the phone number so you can call them). As you need to CALL canon, their number is: 1-800-652-2666 (1-800-OK-CANON), please CALL them, provide all the details and provide this bug's url. Note that in certain commercial systems the more phone calls complaining about a problem, the sooner it's researched. In our system, this is not the case, we fix bugs we can fix, and this isn't a bug we can fix, so adding comments just annoys us.

"...In our system, this is not the case, we fix bugs we can fix, and this isn't a bug we can fix, so adding comments just annoys us..." Well sorry it annoys you but how come printing on my Canon 4500 worked fine before FF 3.x.x and now it doesn't. I haven't changed any Canon drivers - it's a Mozilla problem - stop dodging the issue and fix it please!

Terry: https://bugzilla.mozilla.org/page.cgi?id=etiquette.html Their printer driver is crashing. The end. Just because it's triggered by Firefox doesn't mean anyone here has control over it. Just because there may be something in Firefox it doesn't handle well does not make it Firefox's fault. Do you honestly think we'd pretend we couldn't fix a crash? There is no magic "fix it" wand.

Dave: "Their driver" - this affects a number of diferent Canon printers and drivers. Check the forums. If FF2.x.x worked and FF 3.x.x doesn't then surely it's a backwards compatibility issue for FF. I haven't changed my Canon drivers from installation day and which worked fine on FF2. I have emailed Canon with all details with links to this bug report and the forums. Hopefully someone there might help us.

(In reply to comment #34) > Dave: "Their driver" - this affects a number of diferent Canon printers and > drivers. So? That would just mean that whatever is crashing is shared code among their drivers for different models. > If FF2.x.x worked and FF 3.x.x doesn't then surely > it's a backwards compatibility issue for FF. If true, what you're saying is that their driver can't handle newer Firefox, not the other way around. On no planet is a crash within the driver (and it is, if you can read comment 5) not a problem within the driver. For the last time, just because Firefox is tripping over their land mine does not mean that Firefox is the cause. At most, if we're lucky, a work-around could be made in Firefox, and that is not a fix, just a band-aid. Furthermore, even if there is an underlying problem in Firefox here (in addition to whatever is crashing on their end) there's no way anyone here can debug someone else's software to find it. And EVEN IF all of the above was some sort of evil conspiracy, no amount of complaining is going to change it. > I have emailed Canon with all details with links to this bug report and the > forums. Hopefully someone there might help us. That is the hope. By the way, just to clarify, you're getting this in the current version of Firefox 3.5.2? (all the others above were just on 3.0.x)

I'm no techie,but I do not see why Canon, Apple and Firefox wouldn't all be trying to solve this, especially as the printer that crashes for me a Canon MP480 came with my new IMAC which I purchased in April 2009. April fools Day, in fact. Should have known better

Firefox 3.5.2. Crashes on every 3.x.x Thanks for your help............

Terry: Thanks. Paula and everyone else: Yeah, Canon should be working to solve this. See comment 31. To anyone just reading this and not the rest of the bug: Some people resolved their problems with a driver upgrade. See comment 11 & 12. Others, apparently, did not. As has been said many times before, louder is not necessarily better. Additional "I get it too" comments are quite useless in most cases. Please, I know this is frustrating, but this is not the place to vent. Only post here if you have something new to add such as a version number that fixes something or a new reply from Canon. For Mozilla support, go here: http://support.mozilla.com Please let this be the last comment here for a while. We don't need any more clutter here.

@ Dave First response from Canon - not very promising ref not being able to comment on third party developer's comments. I'll post back with any developments. Thanks ======================== I am sorry to hear that you are having problems with your canon product. With reference to your enquiry, I will pass on your comments to the relevant department. I must advise that we are unable to comment on forum comments or comments by third party developers. As you state yourself, the printer worked prior to the upgrade. I hope this information is of use to you. If you have any other queries, or need any other information, please do not hesitate to reply directly to this email, and quoting the reference number:- 364857

This appears to be fixed!!! At least for me and my GF. Mozilla version 3.5.2 OS X version 10.5.8 I doubt it is a printer driver problem, as stated in the dell printer sister bug of this one, it happened with three different printers, and even happened with a fresh install of OS X (no printer drivers) printing to pdf. Either Firefox or Apple has fixed this for me. If everyone else could post their results I would appreciate it. Hopefully it's not just a fix on our Macs.

Not fixed on my CAnon IP4500/FF 3.any version. I'm still waiting for a response from Canon as Mozilla are not going to do anything. (See post 39)

I'm still having the same problem, with different Canon printers - in my case both a Pixma Pro 9000 (by USB) and an MX850 (by network). So are a lot of other people (see the forum postings on http://forums.mozillazine.org/viewtopic.php?f=38&t=846285&start=30)

http://forums.mozillazine.org/viewtopic.php?p=7245835#p7245835 is an interesting bit of information from Canon Tech Support.

Upgraded to Snow Leopard + 10.6.1 update. Problem fixed. (Canon IP4500 FF 3.5.3)

(In reply to comment #49) > Upgraded to Snow Leopard + 10.6.1 update. Problem fixed. (Canon IP4500 FF > 3.5.3) and in several postings since this, some people have resolved this by installing new canon drivers, or updating firefox http://forums.mozillazine.org/viewtopic.php?p=8294625#p8294625 http://forums.mozillazine.org/viewtopic.php?p=8240485#p8240485 http://forums.mozillazine.org/viewtopic.php?p=8243985#p8243985 those who updated firefox and are now working may have picked up fixes Bug 396680 - [10.5] Crash on attempt to print to unreachable HP printer [@ objc_msgSend - HPSmartPrint@0xe4cc] xref for users of trunk builds Bug 520494 - Implement the Cocoa print dialog in a way that works on 10.4 => invalid

Purchased new MG3500 as a replacement for the E12 4100 with the crash problem and no drive updates planned. Problems seems to have intensified with new printer. New Canon ColorQube MG3500 will not print more then four pages before it prints half a page and stops with an error "early eof reading control byte".
