How to use ramdisk in Firefox on Mac OS X 10.5 Leopard

Using ram as cachedisk in firefox increases productivity of flash (ex. watching youtube).

First you have to do is create ramdisk using this command:

# diskutil erasevolume HFS+ "ramdisk" `hdiutil attach -nomount ram://1165430`

Next step is specify path to ramdisk in Firefox. Open new tab (or window) and type about:config.

Now you have to add new variable called browser.cache.disk.parent_directory with path to your created disk.

Set size of files which will be saved in your diskspace (browser.cache.disk.capacity) – for example 1165430 (550Mb).

To enable memory caching click double on browser.cache.memory.enable.
