Well, that is unfortunate. Firefox won't start properly, something to do with some bit of XML interface thingy by the look of things.
@doenietzomoeilijk weird :o is it cause by some extension maybe?
@vancha no clue, it was fixed by starting Firefox in safe mode and doing a Refresh, which dumps everything and starts fresh (and, in my case, shortly afterwards installs all my extensions and bookmarks, because Sync).
