Try about:performance ?

Thanks. That's a good step in the right direction. But it shows stats on just four tabs-- fewer than half the number currently open. There's great info there, just not enough.
Danke++
It seemed to show all mine. Are all your tabs in one window? If not, is it possible that some belong to a different firefox instance?
The tabs have to be "active".
For example, if you reload FF, only one tab per window is active.
First, I had to close down FF that was giving me trouble... something was running my CPU way too much, near to locking up my entire system. I closed about four or five tabs which weren't essential, then restarted FF. So far no obvious problems. But this sort of problem happens regularly, though more often it's the RAM which is eaten up, driving swap crazy, and slowing down my system that way. So currently I'm looking at a a system which is behaving.
The term "active" is too slippery for me, maybe for FF as well. Looking at about:performance, I see entries for five web pages One is for about:performance itself (useful to display its existence?!). Another is for a web page in the same FF window as about:performance. A third is for a web page open in the only tab existing in a different FF window, a window which has been minimized since I started FF. The other two are entries listed are for two tabs in a totally different window.
Currently there are five other FF windows open, all but one of which are minimized. All five windows have multiple tabs. FF's about:performance lists none of them and none of any of their tabs. I'm not seeing any commonality in the five entries listed by about:performance which distinguish them from all the other tabs in all the other windows.
It's my experience that most of the webpages in the world run some javascript or similar. And I highly suspect that's the cause of the problem: some bad code which is running up the CPU (but more often RAM). Well, the problem might also originate from one of the add-ons I've installed... that may be worth a look the next time the problem comes up. But intuition is telling me the problem is more in the particular webpage.
a handy script I employe: </usr/local/bin/psfind> #!/bin/bash # Loop until all parameters are used up echo "USER PID %CPU %MEM VSZ RSS TTY STAT START TIME # COMMAND" while [ "$1" != "" ]; do ps -A auf |grep -i $1 |grep -v grep|grep -v psfind shift # Shift all the parameters down by one done then, psfind firefox | less -S will display the firefox windows with cpu usage and pid when you determine which is causing concern, kill that pid and look to see which window is no longer available and you will know where the problem is. You can dive deeper after gaining this knowledge example with lines abreviated for better display: USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND paka 5141 10.1 4.3 5031336 1607188 ?
