I downloaded Firefox version 4.0.1 today on a windows vista PC, and now I can't access firefox at all. I try to open it, but no firefox windows open up. Is there a way to fix this?

But when I try to uninstall the programme to try and download it again, it won't let me because it says firefox is still running, yet no windows are open.

I found that if I had a complicated session (lots of tabs open) that Firefox had trouble opening the first time (it has been fine since). To fix this I deleted my session files in my Profile after making a copy of them.

Here's how if you're still having trouble:

On Windows, your Profile is in "%APPDATA%\Mozilla\Firefox\Profiles" - paste that into the Run menu (Windows key + r) and look for session.rdf, sessionstore.bak and sessionstore.js. Delete those, restart Firefox and you should be on your home page. Good luck!
