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?
