Could you share your use case for this? The odd time I've benefited from viewing multiple tabs at once, I just split them to two windows and resize them. I'm guessing this is just faster?
Something I wanted this for a while ago: quickly and easily displaying two tabs during a single window share on a zoom call, if displaying two things to compare or when running a planning meeting.
I'm not a Firefox user but I use split tabs often in Vivaldi when I need to manually enter data from one system into another system. Splitting the tabs instead of dragging one into a separate window keeps all the tabs contained in the same tab workspace. I have several workspaces and I don't want to accidentally lose an important tab because I dragged it out into its own window and forgot to drag it back.
edit: typo
This! And, often it means less "chrome", (eg title bars or side panels or whatever) getting in the way.
It's not a use all the time thing, but instead a tool that is just really handy.
Network admin stuff when you need to monitor a bunch of devices, security feeds across cameras (especially when they don't combine into a single PVR system) and more.
I have had people report it as a bug for a web application on Edge. I too don't see a use for it still.
