Firefox freezes computer 100% cpu usage when juno.com site is open
I can have many windows open without problems but often when Juno.com webmail website is open it will freeze the computer and requires task manager to shut down firefox. I have already disable flash plugins. That one website is the only one that produces the problem. Windowws xp pro
Chosen solution
by cor-elStart Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
- Do NOT click the Reset button on the Safe mode start window or otherwise make changes.

Question owner
Safe Mode seemed to sidestep the problems SO I cannot tell a lie, each link provided above noted to save time "Use the Reset Firefox Feature". That's what I did. All does seem fine now. I will be back if the symptoms recur. Thanks for the help and direction to the Reset button that I never knew existed even though I have been with FF since the fox was a little cub.
