Firefox 61.0.1 on Xubuntu 16.04.I have tried Chrome, Midori, and lots of other browsers, but they all fail to provide all the functionality that I need. And they tend to be just as gluttonous as Firefox anyway. The big problem is CPU usage. The computer has 16GB of RAM, and I never come close to using all of it. But Firefox usually takes most of the CPU. This leaves me little for ripping and encoding movies, which is also very CPU intensive. I found a little program called cpulimit, which doesn't quite work. I launched Firefox yesterday with 'cpulimit -l 20 firefox' and right now Firefox itself is taking a mere 3% of the CPU, but there are currently four Firefox child processes ('contentproc') and one of them is taking 80%. This wouldn't be annoying if it was just a temporary usage while it was loading a web page or something, but it has been stuck at 80% for the past hour, even though all Firefox windows are minimized. The only way to get Firefox to behave is to kill it completely. And if I then re-launch it, even though I have it restore the previous session, it initially takes little of the CPU, but by a couple hours later it is back to taking almost all of it. Any suggestions? _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
Have you started Firefox with Add-ons Disabled (Safe Mode) to identify if the fault is with and add-on or not?
Enter: about:support or go to the "cheeseburger", select "Help > Troubleshooting Information"
Select the "Restart with Add-ons Disabled..." under the "Try Safe Mode" title at the right. This will disable all add-ons and restart your browser.
