Simple Discard Tab

Discards tabs that are inactive for 3 minutes to free up memory, while still preserving the tabs state when you click on them again.

This extension will discard tabs that you have not opened in the past 3 minutes or more (configurable). Only unfocused tabs will be discarded. Tabs which are pinned or are playing music will also not be discarded. When you focus/click on a tab, the tab's contents will immediately load up again. If you hover over the toolbar icon, the tooltip will tell you how many tabs were discarded in the last pass. For example, it will show "(4/9)" to mean 4 tabs were recently discarded out of a total of 9 running tabs. Tabs previously discarded are not included in the total count. This extension requires no special permissions to run, so use it in confidence. If you enable the "read browser history" permission, you can enable a whitelist to choose which website domains should never be discarded.
