Hi,
Normally I have many tabs opened in Firefox. I don’t know how many,
eventually it could be a hundred. Not all are really loaded, tabs do not
load content till you click on them at least once. On firefox start,
only the displayed tab, one per window, actually loads.
So, my normal CPU load for firefox is under 8%. But sometimes it soars,
and it keeps high for hours. Like now, it is using 33%.
The typical culprit is flash, so I routinely block all flash (with
flashblock), till I click on the box and tell it load it. If not, I can
kill its separate process (you see them displaying “ps afxu”).
But sometimes it is not flash, it is something else.
It may be an animated graphic.
Or it may be a script on some page.
So, the question is, how do I locate the specific tab or site that is
overloading firefox, so to close it, or block scripts on it, or one
scrip specifically?
The idea is to find out first which one is the culprit.

I just used the “H” key on top, to show threads. I am seeing something
named “Media State” and another “Media Decode”, at relatively high CPU.
I don’t recall seeing them previously. Their PID changes continuously,
so I can’t see what started them. And I can’t find a file by that name.
