Split-screen/Tab-in-Tab feature (view more than one tab at once)

[KERR]

Currently I'm doing research on a heap of products, and collating into an online spreadsheet. I'm wearing out the Ctrl+Tab keys flicking back and forth, copying/pasting etc!

It would be awesome to "pop-out" a tab and have it "float" on top like what Picture-in-Picture does. I know you can the tab in a new window, resize it, move it etc but it still doesn't stick on-top and has borders that take up space.

I've seen extensions that try to do split screen for tabs but they don't seem to work very well. Thanks!

Split Screen

I love Firefox and will always keep using it but there is a feature just released on the latest Edge update - Split Screen. I have to say Split Screen is pretty cool and can make some of my work efficient.

Mozilla, where is split screen???? We need it
