Having suffered an unstable system for months which was, it turns out, entirely, completely and utterly caused by Firefox in some way and another, and has been completely cured with Firefox release  3.0.10; I'm now wondering if I should 'upgrade' to the newest release?

 I switched off automatic updates as what I have (3.0.10) is completely stable here and I'd much rather it stayed that way.

Has anyone upted to the latest version? and, if so, does it cause you any problems (or not)?

Better late than never but am running 3.5.5 and all has been ok.

Hello,

 You have to update firefox which will be better for you when you surf your internet with it. Its provides you new features and different quality.

 Thanks
