As a tiling window manager user, I am really frustrated with mainstream web browsers. They are an ergonomic disaster for me, forcing me to use the mouse and waste so much precious screen real estate with gray space and redundant tabs. I want to disable tabs and just use windows managed by my window manager. That's what window managers are for! Separation of concerns is a pretty good notion in my book. Emacs can have a server and multiple "frames", so why can't Firefox or Chrome? Someone please tell me this is possible and I just missed it.
With all due respect, I think that this is just the inevitable cost of swimming upstream. GUIs are designed, through and through, to be used with a mouse. Someone who wants to navigate purely with a keyboard just isn't part of the thought process when designing the UI of your browser.
I’m with you and I remember a brief time when Windows ?!? had the nerve to try this with Microsoft Edge (Windows 8-ish). I love workspaces and generally don’t like applications to have internal tabs.
