I have the same problem, I guess we have to wait until they update it.

At least I'm not on my own !!! Have now uninstall completely now and will try and reinstall tomorrow... Most frustrating thing is that If I click around about where it should be I can get to the settings page ...but if I click on that I just get a black box...

Try searching around the firefox support pages and see if you can downgrade to a version. I just recently did that and everything was fine.

I've done that and it worked - thanks! (Bit worried about the security warnings about using older versions though but at least now I can try and find a better solution!)

Now I can see it again - (I couldn't get it to open in safe mode by pressing the shift key before) I've disabled the hardware acceleration and updated to version 33 and all seems well again .

hello lucky67, could you go to the firefox menu ≡ > help ? > troubleshooting information, copy the contents of that page and paste them here into a reply on the forum? this might be very useful in order to find out what was going on and maybe to develop a fix for other affected users. thank you!

Is this what you mean? After reinstalling 33 and having the same problem I had actually uninstalled Firefox, then realised I'd lose all my setting so did a system restore (but firefox wouldn't open - missing O?XP - think the ? was a C). Found version 31 downloaded that, turned off hardware acceleration and then updated back to 33 - and it working fine now Hope it helps ...
