We're sorry to hear that Firefox is crashing. In order to assist you better, please follow the steps below to provide us crash IDs to help us learn more about your crash.

2. Copy the 5 most recent Report IDs that start with bp- and then go back to your forum question and paste that into the "Post a Reply" box. (Please don't take a screenshot of your crashes, just copy and paste the ID's. The below image is just an example of what your Firefox screen should look like)

Thank you for your help!

More information and further troubleshooting steps can be found in the Troubleshoot Firefox crashes (closing or quitting unexpectedly) article.

Hello,

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.

Some of your crash reports weren’t sent to the Mozilla Servers.

In the address bar, type about:crashes. Note: If any reports do not have BP in front of the numbers, click it and select Submit.

Start Firefox in Safe Mode {web link} While you are in safe mode;

Type about:preferences<Enter> in the address bar

Select Advanced > General. Look for and turn off Use Hardware Acceleration.

Poke around safe web sites. Are there any problems?

Then restart.

I deacticated hardware acceleration and started with deactivated add ons. Still, firefox crashes, sometimes after 5, sometimes after 10 minutes, nit in regular intervals.

Your crash reports are showing a js::jit crash signature which is a crash in the JIT (Just in Time) compiler in Firefox. You can try to disable JIT to see if it'll alleviate the issues. Try setting javascript.options.baselinejit to false in about:config:

• Navigate to about:config in your Address Bar
• Press the "I'll be careful, I promise!" button to proceed
• Search for javascript.options.baselinejit and set it to false by right clicking the pref and selecting Toggle.
• Restart Firefox and see if it works properly.

If you don't see any difference after using Firefox for a while with the JIT compiler disabled and you still get crashes, follow the steps above to re-enable it and post your newest crash reports.

Dear Moses, dear other users,

many thanks for your tipp, but unfortunately, it did not solve my problem. I disabled javascript.options.baselinejit, but firefox still crashes in irregular intervals. These are the last carsh reports:

Do you have another idea? These crashes while working are annoying!

Many thanks in advance

Some of your crash reports weren’t sent to the Mozilla Servers.

In the address bar, type about:crashes. Note: If any reports do not have BP in front of the numbers, click it and select Submit.

All the new reports say JavaScript but with different processes.

Some added toolbar and anti-virus add-ons are known to cause Firefox issues. Disable All of them.

Dear Fred,

I erased all Java from my computer and see whether this might help. This are the recent crash reports, now all starting with bp. I followed your advise and submitted those without bp:

Do you have another idea what might cause the problem?

Thanks and best

One crash is from Shockwave. The others I don't know.

Note, one of the posts was flagged as Solved Problem. Please turn it off.

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.

JavaScript errors may be caused by a corrupt registry entry. Use a good registry repair program. You can also try this;

Click on the start button (windows logo on Vista). In the search field type cmd. Right click on that icon then select Run as Administrator.

One of these commands should work on your system.
