Until about a week ago I was using Firefox 3.5.5 quite happily, but then my machine auto 'upgraded' it for me.
Since then my machine has really struggled.
Within an hour of installing, Firefox crashed - twice. >:( >:(
Regularly now it kills my machine. I have to kill it off and restart, sometimes that doesnot work and I have to reboot the box. >:( >:(
After about an hour of use it just goes into CPU overload, consuming 80-90% of the CPU, no page faults though, so its not a memory issue. If I go and do something else (watching the Olympics) and come back an hour or so later, its still thrashing away.
Its now becoming such a regular feature, I've gone back to IE. :(
