      Looks like “tree style tabs” extension on Firefox.

      Alternatively you can try Floorp browser (fork of firefox) which includes this by default. It’s like a mixture of Vivaldi and Firefox, but mostly Firefox.

    What extensions/configs do you use for tabs managing? It seems like you have 2 columns for that.
