When Firefox crashes it displays a dialog, I give permission to send a report to Mozilla, and the dialog says there was a problem submitting the report.
Firefox page "about:crashes" lists 2 crashes today, 2 crashes a few days ago, and some older ones.
When I click a crash ID for example db81f3f6-cd44-4ce8-8268-de23913c35d9 (https://crash-stats.mozilla.com/about/throttling) it gets a "Page not found" (https://crash-stats.mozilla.com/about/throttling).
Upgrading from Firefox 30 to Firefox 31 did not change the frequency of crashes.

Do a malware check with several malware scanning programs on the Windows computer. Please scan with all programs because each program detects different malware. All these programs have free versions.
Make sure that you update each program to get the latest version of their databases before doing a scan.
- Malwarebytes' Anti-Malware:
- Microsoft Safety Scanner:
- Windows Defender:
- Spybot Search & Destroy:
- Kasperky Free Security Scan:
You can also do a check for a rootkit infection with TDSSKiller.

I figured out that a few of the crashes succeeded in uploading their dumps. The reason for crashing is running out of memory. Even under 64-bit Windows with more than 4GB of RAM and many GB of pagefiles available, Firefox runs in a 32-bit process with limited virtual address space.
I have around 50 tabs open to ordinary information sites. At home I have a tab open to Youtube playing music, but at work I don't. I don't know how these tabs use more than 1.5GB of virtual RAM. But they do, and Firefox gets confused.
I read that Bugzilla already has OOM (out of memory) marked as a big reason for crashes, and Mozilla's volunteers marked it as WONTFIX.
I understand that Mozilla's volunteers are volunteers and I can't complain about WONTFIX. But the attitude is equally offensive as Microsoft, blaming users when the maker's bugs are the maker's bugs.
Java Script is mentioned in the crash report.
Try Firefox Safe Mode to see if the problem goes away. Firefox Safe Mode is a troubleshooting mode that turns off some settings, disables most add-ons (extensions and themes).
If Firefox is open, you can restart in Firefox Safe Mode from the Help menu:
- In Firefox 29.0 and above, click the menu button , click Help and select Restart with Add-ons Disabled.
- In previous Firefox versions, click on the Firefox button at the top left of the Firefox window and click on Help (or click on Help in the Menu bar, if you don't have a Firefox button) then click on Restart with Add-ons Disabled.
If Firefox is not running, you can start Firefox in Safe Mode as follows:
- On Windows: Hold the Shift key when you open the Firefox desktop or Start menu shortcut.
- On Mac: Hold the option key while starting Firefox.
- On Linux: Quit Firefox, go to your Terminal and run firefox -safe-mode
(you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
When the Firefox Safe Mode window appears, select "Start in Safe Mode".
If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to figure out which one. Please follow the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article to find the cause.
To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.
When you figure out what's causing your issues, please let us know. It might help others with the same problem.
I clicked the menu button, clicked the help button, and clicked to restart Firefox with Add-ons Disabled. The Firefox Safe Mode dialog came up. I clicked the button to Start in Safe Mode.
I clicked on the Help menu - Firefox Health Report. It says 1 Add-on is enabled and 0 Add-ons are disabled.
This is safe mode?
The Add-ons Manager (about:addons), left-hand tab for Extensions, says "! All add-ons have been disabled by safe mode." Troubleshooter 1.1a is disabled. There are clickable buttons for Disable and Remove, but no button for Enable.
So which add-on is enabled? I don't know how to find it.
Appearance, Default 31.0, is also disabled. I wouldn't have guessed by looking at the Firefox windows; I only noticed when looking through the Add-ons Manager.
Windows Task Manager says that 4 processes are executing instances of FlashPlayerPlugin: C:\Windows\SysWOW64\Macromed\Flash\FlashPlayerPlugin_14_0_0_145.exe
Oh yeah, the Add-ons Manager tab for Plugins says that Flash will always execute instead of asking to execute.
So even in safe mode, Flash is enabled instead of asking?
Good news is that this setting seems to be helping, though I don't really understand it since Flash is active. After restarting in safe mode, Firefox has run for more than 3 hours of CPU time and has occupied more than 2,000,000 KB[*], and yet has not crashed.
I still don't know what's occupying most of that memory. At home I'm playing music on Youtube, which takes its share of CPU time, but apparently not much memory. At work I don't do that, but tabs displaying ordinary information still occupy nearly 2 GB and Firefox's crashes are probably due to out-of-memory.
[* I nominate the word "disunit" for memory occupancy shown by Windows Task Manager. 2 * 1024 * 1024 * 1024 would be 2GB in binary units, 2 * 1000 * 1000 * 1000 would be 2GB in decimal units, and 2 * 1000 * 1000 * 1024 is Microsoft's disunited combination.]
Java, Flash and some others are in the add-ons manager under Plugins. Go there and Disable Everything as a test.
In the add-ons manager I see a setting for Firefox to ask before activating JAVA, which is set by default and I have not changed it. I have never been asked and I assume JAVA has not run at all.
In the add-ons manager I see a setting for Firefox to run Flash without asking, which is set by default and I have not changed it. I understand your suggestion to change it. I have mixed feelings about whether to try it.
In safe mode, only add-on extensions and user setting are disabled. Plugins are not unless you disable them.
Please post your latest crash reports. Note: If the report does not have BP in front of the numbers, click it and select Submit.
You can try to disable hardware acceleration in Firefox.
- Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
You need to close and restart Firefox after toggling this setting.
In Firefox Safe mode these changes are effective:
- all extensions are disabled (about:addons)
- default theme is used (no persona)
- userChrome.css and userContent.css are ignored (chrome folder)
- default toolbar layout is used (localstore-safe.rdf file)
- hardware acceleration is disabled (Options > Advanced > General)
- plugins are not affected
- preferences are not affected
NoScript is described as an extension. All extensions are disabled when Firefox is running in safe mode, right?
I understand the suggestion to disable hardware acceleration in Firefox, but again it seems odd. When video drivers crash they ordinarily give BSODs, or more recently Windows 7 can restart a bug-ridden video driver instead of BSOD.
"In Firefox Safe mode these changes are effective:
all extensions are disabled (about:addons)"
Yes, I noticed that.
"The prefs aren't modified if you enter safe mode as this disabling is done internally."
I restarted Firefox in safe mode again. We'll see what happens.
Now Yahoo Mail doesn't work.
I'll leave basejit disabled and we'll see if it helps.
