Sleep Mode
Sleep Mode will temporarily put all tabs to sleep mode for saving RAM memory, saving battery and make your computer/laptop faster.
Sleep Mode: Save RAM & Battery, Speed Up Computer
'Sleep Mode' is a Firefox add-on that puts your inactive tabs to sleep. This saves precious RAM memory, increases battery longevity, and increases the speed of your computer or laptop. Despite putting inactive tabs to sleep, your working tab remains active and responsive. As soon as you switch tabs, the new tab wakes up, and the previous one goes to sleep, ensuring non-disruptive productivity. Opening a sleeping tab wakes it up instantaneously. The extension allows settings to ignore pinned tabs, tabs with audio playback, Google Docs and Office Online tabs. An automatic sleep timer can also be set.

User reviews
An excellent application, unfortunately it doesn't work properly.
I'd like my tab to sleep after X minutes without me coming back to it. To allow me to go back and forth without constantly reloading, example: if I come back to this tab after leaving it in less than a minute, don't put it in sleep mode.
