I generally have a “home” Firefox window with my most used tabs pinned. Sometimes I close it before another window, so I was frustrated to “lose” it and having to redo my pins. But recently I discovered this feature. Joy!

  • I can still feel the pain when it’s 2 AM and you meant to Ctrl + Shift + T and you’re muscle memory leaks in and hits you with the Ctrl + Shift + W.

    FYI there’s a confirm close option that will mitigate this terrible scenario, for anyone that’s been there before.
