Speed up Firefox page loading time

Instead of loading cached images and data from the hard drive, it loads from memory, which is a lot faster. It turns out, though, that Firefox can do this without using a RAM disk -- you can simply do it with about:config.

Just follow these instructions -- and don't worry, if you mess it up, you won't break anything.

  • Type about:config into the address bar
  • Type browser.cache into the Filter field
  • Set browser.cache.disk.enable to false (double click it)
  • Set browser.cache.memory.enable to true (double click it)
  • Right click > New > Integer; type browser.cache.memory.capacity; press OK
  • Type in 100000 (this is equivalent to 100 megabytes); press OK
  • Close all Firefox tabs and windows, and then restart the browser
