I have 4GB RAM on my computer and I could see using this command:

ps aux --sort=-%mem | awk 'NR<=10{print $0}'

that this process consumes a lot of memory and cpu:

/usr/lib/firefox/plugin-container -greomni /usr/lib/firefox/omni.ja -appomni /usr/lib/firefox/browser/omni.ja -appdir /usr/lib/firefox/browser 463 tab

And, in the second place, follows firefox process.

I do not know if I can do something to avoid or reduce the RAM's consumption. I appreciate your help. Thanks!

Kill all the firefox processes and try a Chromium-based browser. If you really have to stay on FF, then try to reduce the amount of things like tabs, plugins, etc. loaded in your firefox session.

  • Yes, I really need to stay on FF. The strange thing is that I do not have a lot of things like tabs, etc. Only 5 tabs, and one extension (ad block).

  • I changed this parameter: layers.acceleration.force-enabled for true in about:config of FF. And now memory available decreases and cpu increases a little, but is fine because it works everything better.

  • In my experience sometimes a single tab, that loaded a badly made website, could cause some high memory/cpu usage.
