A standard computer nerdy post from me, I ran across some settings to tweak to stop Firefox from caching files to disk.
Check the about:config page and set browser.cache.disk.enable to false
Then create a disk.cache.memory.capacity preference of type integer and set it to however much memory you want firefox to eat (in kilobytes). In the screenshot below I set mine to 1gigabyte which may be overkill. I’ll adjust it if it becomes an issue.
Disclaimer: If you have any doubt in why you’d want to change that setting either don’t mess with it, or email mike and ask
Some random other SSD related optimizations:
Disable System Restore:
Start –> Right-Click Computer –> Properties –> Advanced System Settings –> System Protection –> Configure –> Turn off system protection
Start->cmd->right click and run as administrator –> powercfg –h off
