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!

Works super well, makes my Mac run 10x smoother on heavy browser load.

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

Thanks to the author.

This extension doesn't work, the unload tabs still occupy the same memory space.
