pinned tabs work for me, but edge has a nice grouping feature, I hope it'd be similar to it

Right... I use multiple browser windows as tab groups. Tried tree tabs, but since I keep one window per topic I rarely get enough tabs open to need them.

So how is that different from their official addon?

Multi-Account Containers by Firefox

Firefox needs passkey support ASAP

awesome news, i loved the tab groups back when i was using edge.

I remember the first time they ditched it, I didn't get accustomed to the feature because I knew what was coming. Around that time they acted very googley adding and removing features, luckily firefox has become less ADHD.
