Is there a way to reduce the memory usage of Firefox?

This works wonders!

  • Check your Extensions and Themes. (By running Firefox in safe mode.)
  • Check the Plug-ins.
  • Clear Download History.
  • Restart Firefox Periodically.
  • Assign Memory Cache on Firefox. (browser.cache.memory.enable and browser.cache.memory.capacity)
  • Release Memory when Firefox is minimized. (config.trim_on_minimize)

I've been testing this for a few days and am very impressed. Reduced from average 150MB to 60MB

Of course, it's an extension so has its own footprint!
