It's just a clone of chrome feature. Cool they impelmented it too. I just don't see this "we listen to the community" more like "we are just trailing behind chrome"

I used FF for 20 years and moved to Edge a few years ago. I thought similar about this feature, Edge has had tab groups and vertical tabs for a long time now.

I really hope their implementation on mobile is better than Chrome's. I prefer no tab groups on mobile over what Chrome did.

Opera had vertical tabs and groups in 2010.
