Fixing Firefox’s Voracious Appetite for Memory

firefox-128.pngOk, so its not really a fix… more like a work around. But so far this seems to have worked to help throttle back the Firefox browser’s design to cache pages in memory:

  1. Go the address bar of firefox (where the “http://” usually is entered) and type “about:config”
  2. Look for “browser.cache.disk.capacity” and click on it.
  3. Change the default 50000 to a lower value. It was recommended that if you have 512Mb RAM, you should set it to 15000.
  4. Restart Firefox.

So far my memory consumption, with a ton of tabs “On”, has been hovering at 80Mb. Much better than the previous 240Mb it used to consume.
