It stopped working a long time ago and extension is now abandoned.

This extension has been a lifesaver—it helped me fix all the memory leak issues I was having on YouTube.

Works as expected. Very useful for batter life and old devices with low RAM and weak CPU.
It is must given today's badly optimized and scripts entangled mess we call a web. Not so much from security POV but at least idle means idle again.

This addon is beautiful and a lifesaver and I love it.

My only gripe is that the name and "discard" terminology is misleading; I'd have tried it way sooner if not for that.

A must-have extension for anyone who opens a bazillion tabs all at once, and probably even for people who only open a few (since it doesn't take all that many before Firefox begins to slow, even with fast PC).

I don't know why Firefox doesn't handle unloading tabs even half this well natively, but it really doesn't. Firefox runs so much better with this installed.

I appreciate the detailed options very much, as well. You can customize it to your liking.

this has just saved me from losing over 300 tabs right now
