Three red flags of malware:
Does things without permission ✅
while doing this it takes a lot of power ✅
it is difficult to remove ✅

Please explain to me why theese flags of malware are all true for this extension
Mozilla Firefox (136.0.4) Windows 11

Can't open 600 tabs

one of the best TAB extensions. It saves me a lot of trouble having a lot of opened tabs.

Keeps the open tabs closed :-) Thus saving a lot of memory, and my browser starts much faster

used to be good - now can't get it to run in Firefox, whereas in Chrome is fine
