There's a similar thing shipped in Chrome now called Tab Groups, you just have to enable it behind chrome://flags.
In my view it's nowhere near as nice as it is on Firefox, with site isolation (Facebook, Google, Twitter, reddit), temporary containers, and a myriad of other add-ons that improve managing them (keyboard shortcuts and transition rules are the two I use the most).
