How to reduce FireFox's memory usage

After half a day's browsing FireFox normally eats up a load of RAM, you can reduce this by up to a third by turning off it's memory cache.

Now this should technically slow down your web browsing, but I did not really notice the difference as pages are still stored in the disk cache.

To do this follow the instructions below:

  1. In the address bar of FireFox type about:config
  2. In the filter bar type in browser.cache.memory.enable to filter the configuration settings.
  3. Double click on the config line found to set it to false.
  4. Restart your browser.
