Firefox won't access Gmail

[Columbo]

I want to switch from Chrome to Firefox but everytime I try to access Gmail I get a 'Page is not redirecting properly' message.

I've cleared, deleted and reset just about everything I can with no luck, has anyone got any ideas?

Make sure FF isn't running
In Run enter the following: %appdata%
remove the folder called Mozilla

Start FF

If that doesnt work then try uninstalling and reinstalling FF

Still issues after that? Try running a portable firefox.
