Why can't you guys keep FireFox from crashing? I need this browser for my College Courses and this is making me angry because it's putting me behind.

It seems like every day I have to restart my computer because Firefox's consistency for staying up and running properly is a complete failure. This is unacceptable; I have College courses that I take online and every time the Firefox browser crashes I lose work and when I lose work I get bad grades in school because you have failed your duty to maintain a browser that you also had to earn a degree to get the job. I'm very distraught over this and I'm very close to using a new browser if you don't square this away like yesterday. Not only do I get bad grades I also have to pay the school back the money if I fail. If I fail this course because you didn't do your job I'm going to make you pay the school back for my trouble.

I never upgrade over the top of existing versions, in case the new one messes up.

Also, always back up your existing Fx or Tb profiles, before doing anything.

If you're not backing up "your work," then you only have 1 person to blame.

When Firefox crashes, it usually records information about what was happening at that moment. You can use the Crash Reporter to submit that data to Mozilla and share it with forum volunteers to see whether it points to the solution. Please check the support article "Firefox Crashes" (especially the last section) for steps to get those crash IDs, and then post some of the recent ones here.

If Firefox is freezing and you are killing the firefox.exe process, then unfortunately no data is captured in that scenario.

If you are getting the Windows crash dialog, there may or may not be any data stored by Firefox.

Could you spend a day using Firefox in its Safe Mode? That's a standard diagnostic tool to deactivate extensions and some advanced features of Firefox. If there are some extensions you cannot live without, see the suggestion after the break. More info: Diagnose Firefox issues using Troubleshoot Mode.

You can restart Firefox in Safe Mode using either:

  • "3-bar" menu button > "?" button > Restart with Add-ons Disabled
  • Help menu > Restart with Add-ons Disabled

Not all add-ons are disabled: Flash and other plugins still run

After Firefox shuts down, a small dialog should appear. Click "Start in Safe Mode" (not Reset).

Any difference?


Alternately, try a couple of the things Safe Mode does for you:

(1) Disable Firefox's use of hardware acceleration for graphics

"3-bar" menu button (or Tools menu) > Options > Advanced

On the "General" mini-tab, uncheck the box for "Use hardware acceleration when available"

This will take effect the next time you exit and start Firefox up again.

(2) Disable ALL nonessential or unrecognized extensions on the Add-ons page. Either:

  • Ctrl+Shift+a
  • "3-bar" menu button (or Tools menu) > Add-ons

In the left column, click Extensions. Then, if in doubt, disable.

Usually a link will appear above at least one disabled extension to restart Firefox. You can complete your work on the tab and click one of the links as the last step.

Hopefully this will minimize the potential causes of instability.

You can also try to disable all plugins and set them to never activate or ask to activate.
