I've checked other questions but can't find any help. I downloaded the new version of Firefox and got blank screens, disconnection etc. I found it totally unusable and loaded Chrome instead.
Has anyone else had these problems? Wondering if it just didn't load properly
It's definitely worth trying a fresh download and installation. There are plenty of people using Firefox 4.0.1 around here and you're the first one that I've seen reporting problems with it.
