simple and easy to use

Not sure whether it is working or not.
Even after discarding most of the open tabs
(~150 ), I couldn't see any noticeable memory usage reduction....
Could someone give some numbers (bytes or percentage)
of memory amount recovered after discard of a (big enough,
for to be trustworthy) number of tabs?

There is no other way for me to open 20 youtube tabs without lagging.

Simple and works well, loaded with settings/preferences so you can really fine-tune it's behavior the way you want it. Awesome!

Game-changer - transforms the performance of my high powered laptop (128GB RAM)

Works, but if I maximize/fullscreen a window over discarded tabs they all release when that window minimizes/resizes

Good extension for suspend tabs, like it~~

It's good
