Firefox - Use memory cache instead of disk cache
Description: If you use Firefox, there’s a way to write cached files to RAM instead of the hard disk. This is not only faster, but will significantly reduce writes to the SSD while using the browser.
Instructions: 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 “browser.cache.memory.capacity” -> value memory size in KB. Enter 32768 for 32MB, 65536 for 64MB, 131072 for 128MB, etc. -> restart Firefox
Note: If you’re going to install RAM Disk on your computer you can change the Firefox cache location to the RAM Drive.
Please, see the section below called –=[ RAM Disk ]=– for the instruction.
