Updating to Firefox 107 breaks autohide tabs feature - it won't work. Very useful but broken addon.

Developers respect privacy and permissions guidelines by only requesting those ABSOLUTELY NECCESARY when installing. No full Website data request on install. Read only permissions by default.
Friendly side-bar interface automatically groups your tabs by host/path. A no-brainer add-on for Devs, hackers, and the casual internet user. Thank you, piro_or.

非常nice

Wow. This thing is seriously awesome. Why this is not how ALL browers are by default is baffling.

Edit: And it turns out to be better at navigating and managing bookmarks better than the actual bookmark manager.

What the smeg ?! It opens the bookmarks sidebar !? How hideous is that ! I was expecting the tabs to cascade from their default position, you know, as actual tabs ! This is mental ! Useless.
