Yeah, ChromeOS is a linux distro that boots chrome and is now being officially split into Lacros (Linux and ChromeOS), but honestly, we should be able to make a “distro” that just starts a DE with firefox or chromium as the main window. Extensions could be written that present the filesystem in firefox or chromium and most users would be none the wiser.
Call it WebOS or something.
Does something like that already exist?
Kind of off topic, but webOS was in fact a thing, but more of mobile OS alternative to android and iOS, first developed by palm, the bought by HP, then sold to LG.

It had a small but active homebrew community, with the HP touchpad being one of the early tablets on the market with an unlocked bootloader and Linux support.
