Tabless Browsing
I wish tabless mode would get more love from browser developers. It was the default design choice for years before tabs showed up. From what I can tell, tabbed browsing was/is popular because the default window managers of popular operating systems are underpowered. On Windows, it's not possible to tab arbitrary application windows without third-party software like TidyTabs or Groupy. In my opinion, the window manager should be taking care of things like tabbing, rather than the application....
