Great! If you don't have lots of RAM memory you need it. It will free all unused the tabs from memory allowing you to open as many tabs as you want to.

Would you please make "Keeps Tabs for This Site [Session]" option togglable?

I use it to pause a tab. It works well, but I wish the icon of the tab that is paused to be more apparent, I can't recognize the tabs that are paused from the active tabs. So I click on paused time sometimes, and they load, and it's absolutely not what I want! @zephyr That's normal. When you pause a tab, it discards the content of a form, you must have known this. You can use form saver for this use, but not tab pausers.

Switched to a new tab to look something up while working on a new post to reddit. Previous reddit tab was discarded by Auto Tab Discard and upon return the title remained, but the text box was cleared. Absolutely unacceptable loss of time and effort that makes me question how safe this extension is to use anymore.
