Sometimes Firefox uses a huge quantity of memory up to 500MB. How to configure firefox in order to use less memory?

Follow these simple steps and you firefox will reduce the memory usage:

  1. Type about:config in address bar.

  2. Right click and add a new integer value browser.cache.memory.capacity (Controls how much memory is used to cache pages) and set it to the 80% of the default value.

  3. Set the value browser.cache.disk.capacity (Controls how much disk space is used to cache pages in kilobytes) and set it to between 5000 or 15000.

  4. Right click and add a new boolean value config.trim_on_minimize (Firefox swaps memory to disk when minimized) and set it to true.

  5. Set the value network.prefetch-next (download all pages with the rel=”prefetch” tag) and set it to false.

  6. Set the value browser.sessionhistory.max_total_viewers (how many pages of history are kept in the back/forward buttons) and set it to a low number for example 5.

NOTE: Modifies on Firefox’s default configuration may cause some errors, apply this hacks on your own responsibility.
