Firefox crashes on startup

Posted

Here's the deal.

From one day onto the next, out of the blue, Firefox (version 18.0.1) refuses to start up. I get the crash reporter screen as soon as Firefox tries to start, stating that firefox has crashed. If I click on "Details" nothing happens. If I click on "Restart Firefox" I immidiately get the next Crash Reporter screen. No Windows updates were installed, and no Firefox updates either from what I can tell. I'm running Windows 7 Pro 64bit with SP1 btw...

So I tried starting firefox in "Windows Compatability mode" using Windows XP SP3. Now Firefox starts, including all plugins, without any problems.

I can also start firefox in "Safe mode" by holding down the SHIFT key when double-clikcing on the firefox icon.

So while in safe mode, I typed about:crashes in the URL bar witch showed the following:

(in the mean time, I have a whole lot more :( )

So then (still in Firefox safe mode) I went into the Add-ons Manager and uninstalled all Extensions. Then I disabled all plugins (which btw are all up to date according to Firefox itself):

    Java Deployment Toolkit 7.0.110.21 10.11.2.21
    Java(TM) Paltform SE 7 U11 10.11.2.21
    Adobe Acrobat 11.0.1.36
    Shockwave Flash 11.5.205.146
    Silverlight Plug-In 5.1.10411.0
    VLC Web Plugin 2.0.2.0
    Wacom Tablet Plugin 2.1.0.2

Then I closed Firefox, but when trying to start Firefox again in normal mode, it crashed again. I have also tried uninstalling Firefox completely, then running a registry cleaner to make sure everything was really gone. Then downloading and installed Firefox 18.0.1 again. But as soon as it started it crashed again.

I again uninstalled Firefox, ran the reg-cleaner but this time I installed Firefox version 9 (which I still had on a backup drive), but this version too, crashes on startup. And I had the same with version 15 which I also still had on the backup drive. But whichever version I install, they all crash at startup unless I start them in compatibility mode or safe mode.

I even uninstalling all the programs which had a plugin embeded in the browser, so there were no plugins left. And again, uninstalled Firefox and reinstaled it. But still Firefox crashes at startup. And finally I even updated my graphics drivers and followed this thread: https://support.mozilla.org/en-US/kb/upgrade-graphics-drivers-use-hardware-acceleration#os=win7&browser=fx18

Since I've done everything I can think off, I'm at a loss as to what the problem could be. So if anyone has any idea, please let me know. I hate to switch browsers, and I don't want to run things in "compatability mode" just to have it working, because it did work before.

in the mean time, here are some more crash reports:

Just a small update... I tried running a portable version of Firefox which I had on my USB stick... same problem.


The same goes for my TOR Browser (which uses Firefox too), it too crashes when the embedded Firefox is started.


Both however, have always worked just fine on the same system and still work fine on any other system I have.


---edit---

Well I finished uninstalling and removing everything Firefox related on my system (also ran the reg-cleaner again). I downloaded and reinstalled Firefox 18, but it still crashes. I ran it in safe mode, disabled the hardware acceleration, and ran it again in normal mode...

guess what... it works again!


The weird thing is, I already tried disabling the hardware acceleration but it didn't work. So why it works now? I haven't got a clue. The other weird thing is... why did this problem occur in the first place... There have been no changes to my system, no updates, nothing.


Ah well, I guess I'll never know. But at least it's working again.


Thanks for the help.

It looks like this is possibly caused by your graphics card. Can you try to update your graphics driver, and if that fails, turn off Hardware Acceleration. Upgrade your graphics drivers to use hardware acceleration and WebGL

Thanx for the quick reply Tylerdowner.

Like I said in my post, I already followed the steps in the link you posted.


...quote... And finally I even updated my graphics drivers and followed this thread: https://support.mozilla.org/en-US/kb/upgrade-graphics-drivers-use-hardware-acceleration#os=win7&browser=fx18 ...end quote...


But that didn't work. However, I disabled the hardware acceleration when running Firefox version 15.

I'll uninstall Firefox and everything related again, and reinstall version 18 again and disable the hardware acceleration again.

I'll let you know.
