*You can skip the first 3 steps in this article if you did the fasterfox thingy in step 2.
4.
Firefox has the ability to write cached files to RAM instead of the hard disk. This is not only faster, but will significantly reduce writes to the HDD/SSD while using the browser.
To change the cache location to RAM:
Open Firefox -> Type about:config into the address bar -> Enter -> double-click browser.cache.disk.enable to set the value to False -> Right-Click anywhere -> New -> Integer -> Preference Name "disk.cache.memory.capacity" -> value memory size in KB. Enter 32768 for 32MB, 65536 for 64MB, etc. -> restart Firefox
5. enjoy your faster browser, I skipped 1 on my fast pc because firefox was already fast.
But step 1 helps if you are low on ram and or have a slow cpu.
