Firefox crashes on install

Hi,

After replacing bad RAM on my Mac (a MacBook Pro 15-inch, Early 2011 with 8G RAM running Mac OS 10.9.4), Firefox (version 31.0) continually crashes on startup, and even on install. I've uninstalled Firefox and removed the entire ~/Library/Application Support/Firefox folder (and its contents multiple times), but to no avail. At this point, the Firefox installer will crash while displaying the import bookmarks screen. It seems that something somewhere has been corrupted, but I cannot figure out what.

Several crash reports for this have been submitted, but they appear to contain much useful info.

cd ~/Library/Application\ Support/Firefox/Crash\ Reports/submitted/ cat * Crash ID: bp-274f9272-c764-4195-9706-1db662140819 Crash ID: bp-6a312491-0d02-4d4a-8e51-09e772140819 Crash ID: bp-98f8c0f3-11f7-4d0d-8608-aeb732140819 Crash ID: bp-c7dd1fe2-62fc-4eac-91dc-64b872140819

Note that the crash report files are named <Crash ID>.txt

Any help is appreciated. Thanks so much.

I do not think that it is a good idea to turn off CoreUI on your Mac.

You can check for corrupted and duplicate fonts and other font issues:

You can also try to boot your Mac in safe mode. Starting up in Safe Mode: http://support.apple.com/kb/HT1455

Signature CoreUI@0x6ef9c

Do you have Core on your computer? Disable it.

CoreUI is the framework on Mac and responsible for drawing element like button on the screen.

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.

Thanks for the responses. I'd like to try this, but when I launch FF, it crashes before I can disable CoreUI. Is there another way to turn this off when FF is not running (i.e. in a config file somewhere)?

Thanks again.

Start Firefox in Safe Mode {web link} While you are in safe mode; Press the Alt or F10 key to bring up the tool bar. Followed by;

Windows; Tools > Options Linux; Edit > Preferences Mac; application name > Preferences

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

Poke around safe web sites. Are there any problems?

Then restart.

Firefox also crashes when I try to start it in Safe Mode, so I'm unable to access the Preferences menu or turn off hardware acceleration that way.

It's not really the best option, but if you still have this problem you can try to install Firefox Aurora from: https://www.mozilla.org/en-US/firefox/channel/#aurora and after that, at the next release (FF 32) you can try again with it.

Aurora seems to work (although FF 32 Beta still crashes on startup). I disabled hardware acceleration on Aurora. Any idea what the difference is here?

Thanks for the (interim?) solution? Greatly appreciated.
