It works, has every setting you could think of and visually indicated inactive tabs. For some reason the add-on does take up quite a bit of resources as seen in about:performance. And it also needs every permission you could think of....

"Discard All Other Tabs" and similar bulk actions have never worked (if you have hundreds of tabs).

Still a good memory saver.

Simple and works really well, automatically makes a huge difference. Runs faster and does not crash. I use it so inactive tabs are there but "go to sleep".

Great extension, and does what it says, but it can be a pain, discarding tabs you don't want to discard, unless you add everything to a whitelist. It would be awesome if this had an option to work opposite to that, and only suspend tabs you add to the list.

This feature is just logical. Thanks a lot for implementing and sharing.

Worlds best extention super useful

Doesn't work, even if trying to discard manually.
