Hello Moiz.

I do not quite understand what you mean by

"After update to 3.6.8, firefox hangs more often then previous version."

Can you please be more descriptive? I would like to help you get this problem solved, as FF should not get worse as it evolves.

Hello Tann3r,

It stops responding on switching tabs or filling a form, after using it for some time. When i check task manager, FF process shows above 45% of cpu usage.

I didn't have any of these problem in previous version.

Thanks for your response.

I have this same problem -- Window dialogs (upload a file, etc) stop responding and pages stop loading. I can click on a bookmark and firefox acts as if it's attempting to load the page, but never does. I have to restart firefox to get any pages to load.

I also noted that if I close firefox it asks me to save and quit as normal... the window disappears, but the firefox process continues to run. I have to manually kill it through the task manager to be able to restart firefox.
