Status: RESOLVED WORKSFORME

Can you please give the links to the corresponding crash reports? (you can find them in about:crashes)

As this report is about firefox crashing on startup, and I do not know where the crash reports are stored on the harddisk drive, I can't provide this information. I did not go back to 26 beta 0.

The error is caused by an incompatible add-on, try the advice here:

Hello Mats,

thanks for the reply. I didn't know about the safe startup.
I couldn't figure out which plugin caused the crash.
I did a complete uninstall of Firefox and reinstalled the latest Beta and reinstalled my plugins.
Now everything works just fine.
Strange.

I managed to solve this by launching in safe mode ( firefox.exe -safe-mode ) and removing "English (GB) Language Pack 25.0", I had noticed there's no update available for 26 yet.

I'm not sure if I can provide much additional info. I've installed the 26.0 release of https://addons.mozilla.org/en-US/firefox/addon/english-gb-language-pack/ now and it works fine.
Like I mentioned, it wasn't available at the time of the release of Firefox 26. I believe an extension is automatically disabled when that happens, so perhaps something went wrong there.
