Please, help me translate this addon into your language!

Simple Tab Groups works across browser instances/windows too. If you select a group in another window, the selected window will jump to the foreground with the chosen group selected. You can even select the specific tab within that group in background browser windows. GIF example

This allows for easy switching between active and pre-loaded tabs across multiple browser windows.
