Genuinely baffling that this hasn't been at least put into development yet. This is obviously an incredibly popular idea. We got grouping on PC. This is the next natural step. Please make this happen so I can switch to firefox on mobile already PLEASE
With the new phone I wanted to try also the Firefox browser (I am using it longterm on my PC), but I was shocked it does not support tab groups. I cannot even think about the switch without them...
