This is exactly what I've been wanting! I've been fighting the Firefox memory hog for much too long, needing to close and restart Firefox multiple times per day. The built-in tab unload options didn't seem to do anything, or maybe not enough. It took me just one day using Auto Tab Discard to get in the habit of whenever I'm finished with a tab but don't want to close it, I right click on the tab, click Auto Tab Discard, and Discard Tab. That keeps my memory usage at bay. I also keep an about:unloads tab open and periodically check to see if I should manually unload a tab that I missed. Unfortunately, you can only unload from the top down, not selectively. But in combination with Auto Tab Discard, I now have no reason to abandon Firefox, which I was thinking of doing. Firefox REALLY needs to have a native way to control memory usage that actually works! (Note: I also use the Simple Tab Groups extension and keep dozens of tabs available for easy access, so Auto Tab Discard works great with Simple Tab Groups.)

I used to love this tab add on but now all these little windows open up on the bottom of Firefox. Why? I do not like that. I used to be able to click on the Firefox icon to open it back up on the bottom of the screen but cannot do that now.

This is exactly what I was looking for and works perfectly for my needs.

There could be a setting to delay the release of left and right tabs discard, for when you are just checking the active tab back and forth, and for when you really know you want the active tab, but loading the left and/or right tab(s) makes it take longer.

I really like this plugin, it solves the problem of opening too many tabs very well

This is a great add-on to lower the memory footprint of Firefox.

It will be more nice if you guys add a keyboard shortcut also!

Don't work
