Work as intended, with great options for customization. I wish, though, it was more visually clear that a tab was discarded (I find the grayed icon hard to read). Thanks!

This is nice, and works very well. I'd like for an option to temporarily disable auto discarding, though, since there are a lot of times when I work with a lot of tabs and I'd like to have all of them available. Thanks.

I consider this to be a mandatory to use addon.
If you have lots of tabs, Firefox does not have any automatic way of preventing them from being loaded forever, eating RAM in the background, and this is where this addon helps greatly.
Unfortunately, some functions do not work, like it doesn't discard pinned tabs at all.

Perfect, other than it doesn't keep the tabs favicon.
