This gave me an idea. It might be a silly idea, I don't know.
Chrome introduced an innovation years ago that I loved: it puts a little loudspeaker icon on any tab that's playing music. Firefox later copied this.
That allows nasty bad-mannered websites with autoplay videos -- such as C|Net -- to be identified and silenced.
Is that auto-play that requires the net connection or just animated GIF? Some email I get has short animated GIFs; easy to tell 'cos the loop time is very short. But I can imagine longer ones emulating a video that make massive demands of memory and (CPU?) one the way down have hit network bandwidth as much as if they were a video.
The current feature the browser has is simply knowing which tab is producing sound. Just that. When you start firefox and it loads the previous state with several tabs and windows, it is possible that firefox or chrome starts blasting sound at full volume, because one of the one hundred tabs is on a page that automatically loads a video (mind, video, not gif) and it plays automatically with full sound. Or a page that has "background" music. Nasty. It is not a CPU problem, just a sound problem. Good luck finding the nasty tab. Now, an idea based on that one comes below:
How about an optional addon that embeds a CPU use histogram into the tab headers, so you can see which tabs are the most CPU-heavy?
Yes, but is that relevant? As far as I can tell the incredibly high load factors are an emergent property of wait times rather than CPU load.
And this is where you are trying to fit my symptoms into this tangent and failing :-)
It's probably not something you'd want on all the time, but for troubleshooting it could be very useful.
Shooting some kinds of trouble ...
I would like that addon. Or, even better, open another tab that lists all tabs with a small photo (so that I can click and jump to any of them), and also displays the resources used by each tab (including CPU load) and allows to pause or stop (kill) a particular tab. Freeze a tab would be interesting. But I doubt that FF can say the CPU load of a tab, because it does not assign a process per tab. -- Cheers / Saludos, Carlos E. R.
