We're sorry to hear that your Firefox seems to be crashing when you open it. Please perform the following steps to give us a crash report ID that helps us find out more about the cause of the crash.

1. Press the following shortcut to get a Run window: [Windows] + [R]. This should bring up a window that contains a text field.
2. In that text field, enter %APPDATA% and press Enter. An explorer window should open.
3. From that explorer window, double-click on the Mozilla folder, then double-click on Firefox and then on Crash reports. Double-click on submitted.
4. Now, you should see a list of files that contain reports. Go to View > Arrange Icons by > Modified to get the most recent files at the top of the window.
5. Open the most recent 5 files with a text editor and copy the IDs.
6. Paste each ID with bp- into the reply window on the forums.

Thanks in advance!

Just a quick comment in passing.

Disable hardware acceleration, and try updating graphics drivers. (& conversely role back current one in Windows, in case a new one is the problem)

• see Upgrade your graphics drivers to use hardware acceleration and WebGL
• and Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems

Also note possibly related /questions/951733#answer-412404 which is also not yet resolved.

This seems related to bug 812683; https://bugzilla.mozilla.org/show_bug.cgi?id=812683

Thanks for your help John99 I disabled the hardware acceleration and restarted firefox and it opened normally without any crash report but to be sure gonna restart entire system.

Firefox has twice now displayed a crash report after Windows Update followed by a "restart" -- in both cases Firefox was still running so was shut down by Windows rather than me. I rarely do a restart with any programs running so was surprised when it caused problems.

         Win7-64bit
         Firefox 19.0.2

Hi patdrummond

You may have a problem with VideoLAN, so try to disable the plugin for Firefox, either in VideoLAN or in Firefox (Tools > Add-ons > Plugins).
