I found it not very useful as it doesn't discard tabs just marks them as inactive. That however isn't the issue. Upon removal it forces you on addOn.com for feedback and opens a tab with this which I find hugely invasive and quite bad taste.

Doesn't do anything. Garbage.

edit: Protip: use Tab Wrangler instead. That one does work and it's easy and intuitive.

My memory usage doesn't really go down and instead my CPU usage goes up, making things even slower than they already were. This literally does the opposite for me.

Unintelligible. The word DISCARD is in no way synonymous with PAUSE. They have completely different meanings. Developer needs to read a dictionary. So what exactly does this do? After "discarding" does the tab still appear? If you select the tab, does it "un-PAUSE" ???

Automatic tab discard does not work.

Doesn't work at all. Using the default settings, all tabs are active, using tons of CPU. How does an addon that doesn't do anything get 5-star reviews?

Doesn't work. The setup for delay doesn't work. The setup for which tab stay online doesn't work. Always suspend all tabs after 1 min. I set 10 or 100 min, doesn't work... Useless..

Absolutely useless!
Eats up the whole memory and requests more and more memory, until Firefox and the system (Linux) doesn't react anymore.

It just doesn't work, won't load any tab once suspended.

doesn't work

It stopped suspending after i turned off thenn upon reuse it wont suspend. biggest problem is i lose urls & cant reload those. im on ff60.0.1 plz help me, thx!
