firefox

When I am doing something etc on hxf It just freezes out of the blue and I have to exit it and open again :l

How long have you had this problem for? Is it for any website you visit?

A problem with firefox is that it loads all the tabs you have open together. Chrome loads each tab independantly so if Hxf froze on it then your other tabs should still function. I know it doesn't solve the problem but I'm just highlighting an alternative.

Latest firefox update, if so.
Well then, try re-installing.

Firefox 3 is a little wild on certain websites. I've had this problem now and again.
If the crash report comes up once Firefox is down, it's usual to be honest.
