For saving battery life and performance I use: https://addons.mozilla.org/en-US/firefox/addon/auto-tab-discard/ https://addons.mozilla.org/en-US/firefox/addon/auto-tab-disc... The plugin basically kills tabs if you are not using them, after you click on them they get restored and forms get refilled. There is also a way to exclude websites, but I have not yet found a site breaks.
