Keep your browser windows in check with labels!
If you've ever wanted to organise your tabs into separate windows, only to find that the windows are near indistinguishable when you minimise them, this is the extension for you! Just open the Window Wrangler popup, give your window a label, and when you next minimise the window, see the easy to identify name appear.
NOTE: This will only work if your window manager displays minimised window titles. Both Windows and Mac do, but I make no guarantees for Linux users.
