I've found Auto Tab Discard very useful for many years. It keeps my browser running smooth, even when I've got upwards of 400 tabs open.

PostScript: Yes, I know I have an open tabs problem

Everything works for me (that I've set it up for) except the option to discard pinned tabs on startup. Logs just say it's not ready. But, this add-on seems to be abandoned atm :(

Great and works perfectly with sideberry

Life saver for 8 GiB of RAM!

Brilliant app. Life saver for computers having low ram installed. Best across the board.

Works great but development seems dead? Last updated 2 years ago as of this post.

All new tabs crash with this extension now. If the add-on won't be updated, there's no point in continuing to use it

i would just like to know when a update will be made because it's been 2 years

Awesome extension. Very useful for managing sleeping tabs automatically and/or manually.

Fantastic add-on. One feature request though - could you add the ability to not automatically reload the tab when viewing a discarded tab. In other words, if I click on a discarded tab, it should show a "discarded tab" page and only when I "click" on the page should it load. The reason is that lots of time I accidentally switch to a discarded tab and then it loads the tab when I really wanted it to stay discarded. This is a feature that the Marvellous Suspender has and I think it would be a great feature addition here.

Lifesaver if you are working with dozens of tabs and tab groups.

It's great for laptops and tablets!

No longer works.
