Speed Up Firefox Page Loading Time

We all know that using RAM disk, we can force the browser to load cached images and data from memory instead of hard disk. However, Firefox can do this without RAM disk.

Here are the steps:

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

You may try using 500000 for 500 MB of cache, or -1 to tell Firefox to dynamically determine the cache size depending on how much RAM you have.
