Basically for those wanting to increase their browsing speeds, and don't want to be stuck every 5 seconds when booting your Linux OS from a slower USB drive, or an SD card,
here's a method that supposed to take care for that!
It's not 100% tested yet, I hope some people who know more about this than me, may correct possible errors in this wiki page.
It begins with adding a RAM DISK to your system. Follow the procedures in this link.
Then return here.
Open a new instance of FireFox, and type in the address bar the folowing:
about:config

Rightclick on anything in the window , select 'NEW' » 'STRING'
Enter stringvalue:
browser.cache.disk.parent_directory
As directory, select the ramdisk. If you followed the procedure correctly it should be located in your
file:///home/user/ramdisk
where 'user' equals the user name of your pc. Press OK, and close all FF windows.
Reboot!
Done!
