(In reply to comment #1) > Please try http://support.mozilla.com/en-US/kb/Safe+Mode I've tried it and I can confirm it happens even in safe mode. Please note that I have a great number (66 :-) ) of tabs open.

Please note that > I have a great number (66 :-) ) of tabs open. By having just one tab open (the bugzilla page I'm editing) the situation looks really better: the CPU is now below 5-6%. By opening 10 tabs, with 2-3 of them using Flash, CPU usage increased again to 20-30% (and this one is still far more than previous Firefox versions). 10 tabs and no Flash (I only opened tabs with no Flash in them) is below 10-15%.

Do you see high CPU usage also when Firefox is idle? Do you still see this issue with the current version of Firefox?

No, I see very less CPU usage in the last Firefox versions and usually plugin-container is the most "voracious" CPU-eater. But we're talking of less than 30% CPU usage with more than 80 tabs open.
