Hm alright, I only know of “spaces” on Firefox (also colour coded, but I don’t think you can collapse them), very useful if you have multiple accounts for Google lets say, but in different contexts (like work or private), you can use that so you don’t have to log in every time.
Firefox Sidebar Addon like Brave or Vivaldi?
There are tons of addons but they are all weird. I currently have lots of pinned tabs and would like to move those to a sidebar....
