Vivaldi (and Edge) have this absolutely wonderful capability that allows me to split one tab into two or four at the same time.
At least in my workflow it's quite useful because I usually work with several tabs open and sometimes two related tabs (say, a document I'm reading and a document I'm replying to according to that one), I know that I can perfectly have another Firefox window open next to it and fulfill that function, but I wish I could do it directly from Firefox.
Does anyone know of an add-on that fulfills this purpose? Or maybe a dev who is developing it?
This is the feature I miss most in Firefox, aside from tab stacking. I used Opera (before Blink days) and later Vivaldi for a long time and tehese features almost made me go back. Me not wanting to use a Chromium based browser was the only thing stronger than that.
I've given up hope on ever getting these features in Firefox by now.
Completely agree.
