Lockable tabs and tab groups

[AmGoth]

Make it so I can right click a tab or tab group and lock it, making it un-closable. If the browser is exited they will still be there when opened no matter if multiple windows are open.

I had a window open with my tab groups, then opened a new private window to login to a second Gmail account, then closed the main window thinking it was the private window. Boom, no more research project data.

With locked tabs, even if I close the main window and have a private window still open, once I close that private window and open a new main window, those tabs and tab groups will reappear.

Yeah it's a good idea, not sure why it hasn't been implemented. Pinning tabs makes them too difficult to see what they are.
