Firefox woes

[Franca]

Has anyone else had any trouble with the lates Firefox update for Windows? Firefox has never given me any grief before, but since the last update it hangs frequently (have not detected a pattern yet) and downloads won't complete. I have to use MSIE (horrors) to download anything. The firefox download window never appears and I am unable to tell what the heck is happening. All that appears at the download destination is a partial file - *.exe.part - and it appears that Firefox is still endlessly downloading but I can't be sure. When close the browser, Firefox the program disappears from Task Manager, but firefox.exe the process continues to run indefinitely (without responding) and has to be ended manually. Aaaargh. I keep checking for updates hoping someone else has had the same problem and they've posted a fix, but so far no joy. Any ideas? I could go back to a much older version of Firefox and it would update again but maybe it would work this time.... Thought I'd enquire here first, though.
