I have tried uninstalling and reinstalling fresh. I have tried disabling all addons and extentions. I have updated my drivers on my computer, and all extentions for firefox. I have updated all my anti-virus and anti-malware programs. I have tried creating a new profile for firefox. I have turned off hardware acceleration. Nothing works.

So I might have figured out what's going on. On the bug report, it states that disabling media.windows-media-foundation.enabled would relieve this crash report. Curious about this, I checked to see if a pref existed. It did not. Of course, I was running nothing but pre-release versions of Firefox (Nightly, Aurora) and I couldn't find the damn pref.

Guess what? 29.0.1 has it.

Thinking aloud

Right now I'm lookin' through your reports and I don't see anything out of the ordinary but it seems like mfplat.dll is the reason why Firefox crashed. mfplat.dll is a Windows Media Foundation Platform file. Previously when this bug was reported, it was back in Firefox 20 or 21. Disabling the media.windows-media-foundation.enable pref in about:config was the solution however, Firefox 29 has since removed that preference. So that solution isn't available anymore. EDIT: I was using Aurora and Nightly to test. AFAIK 29.0.1 HAS this pref in true default.

There is a plug in that is being failed to be disabled. Check in about:config and look for plugin. It may be the one Moses is talking about above, but the bug associated with the last crash is old. And run a virus scan just in case. Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of. Better yet, if you can't open it try a clean reinstall and clear some of those malware related plugins.

Thank you so much! I came across this option when I was trying to diagnose the crash and I didn't have the option for "media.windows-media-foundation.enabled" in the about:config so I gave up on that.

To fix mfplat.dll errors, download the file and reinstall it in the Windows system folder. In some cases, the file must be in the folder with the game or program. For detailed instructions on how to install the DLL and other libraries, see "Help" section.
