It’s good to see this result replicated. The only thing I wish Firefox had natively was tab groups, they’re a really useful feature for various organizing things. Otherwise, they’re clearly one of not the best browser on the market.

Just use “Simple Tab Groups” extension. It’s pretty good. And on top of that you can use other extensions, so that for example all tabs within a group automatically get added to a container (isolating them from other tabs). Really useful when shopping for stuff so advertisers can’t track you around different shopping sites (or at least it makes it more difficult)
