| [FireFox] finding FF tab that is hogging CPU
I occasionally notice that I have a significant slowdown, and FF is taking up 48% - 50% of the CPU time. (On a dual-core system) I already figured out that one remedy for this is closing tabs one after another until the CPU usage is back to normal. (0% - 10%)
Is there any way to know which tab is causing this, so instead of blindly closing everything, I could just close the tab responsible for the high CPU usage?
TIA

Maybe you can see something in Tools->Error Console? |

..., but since most every page use it, that itself is not enough. That's where the flashblock extension is useful. With that extension, it will only happen on the tab where you have clicked buttons to actually display the flash applet.

I've had this issue myself but for me it's 90-100% CPU single core.
all signs point to flash but with the system being so slow I just end task the whole firefox and then reload it and close my un-needed tabs..

| Well, it may not be flash, after all. I have only a single (restore session  ) tab, and it's still 45% - 50% CPU usage.
I'm switching to Safari....
