Could you test in Firefox's Safe Mode? That's a standard diagnostic tool to deactivate extensions and some advanced features of Firefox. More info: Diagnose Firefox issues using Troubleshoot Mode.

If Firefox is not running: Hold down the option key when starting Firefox.

If Firefox is running: 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

and OK the restart.

Both scenarios: A small dialog should appear. Click "Start in Safe Mode" (not Refresh).

Then if Firefox starts and runs, please:

(1) Remove the old Firefox Ad Killer extension

Open the Add-ons page using either:

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

In the left column, click Extensions. Then you should find it on the right.

(2) Disable hardware acceleration of graphics

"3-bar" menu button (or Firefox menu) > Preferences > Advanced

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

(3) Disable MP4 decoding

(A) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful.

(B) In the search box above the list, type or paste media and pause while the list is filtered

(C) Double-click the media.apple.mp4.enabled preference to switch it from true to false

The next time you exit Firefox and start it up normally (not holding down the option key), is it any more stable?

Hi, Thanks for you help.

I tried using safe mode, it still crashes.

I went again to about:crashes and clicked on the ones that didn´t start with "bp", there was some sort of processing but I didn´t see the submit button.

You appear to be using Firefox 35. That is old and not supported, yet you are using OS X 7 and so should be on the latest Firefox Fx 40.0.3. Please see and follow the instructions in

• Update Firefox to the latest release

If you do then still have problems try in Firefox's safe mode and post the relevant Crash ID in your next reply.

Thank you! That worked.

Glad to know it is working again. Thanks for letting us know.
