Move Firefox’s cache to RAM

posted in: Tutorials | 0

firefox-256Since your computer can access data in RAM faster than on a hard drive, moving cached data to RAM can improve your page load times. In Firefox, all you need to do to move your cache to RAM is open up about:config and make a few tweaks.

Once you get into about:config, type browser.cache.disk.enable and set it to false by double clicking on it.

You’ll then want to set browser.cache.memory.enable to true (mine seemed to already be set as such), and create a new preference by right clicking anywhere, hitting New, and choosing Integer. Call the preference browser.cache.memory.capacity and hit OK.

In the next window, type in the number of kilobytes you want to assign to the cache (for example, typing 100000 would create a cache of 100,000 kilobytes or 100 megabytes). A value of -1 will tell Firefox to dynamically determine the cache size depending on how much RAM you have.
