@skjern yeah, that's cool and all, but you're using extra RAM things that should be included by default.
Yes, that is true, in my case it is ~10mb of extra RAM usage. I guess my computer can take that 😉
Personally I refuse to install extensions for things I just need one functionality - in my case that's "reopen closed tab". Now I have to go to Menu > Recently Closed tabs, which are three clicks + moving the mouse all across the screen, where before it was just right click, gesture, release.
for me it was also that functionality that was missing, and the addon does the trick.
