Gregory's ServerWouldn't that entail all of the downsides of using Gecko (tiny market share, poor support from websites) without the relatively good brand recognition of Mozilla? There's lot of FF derivatives out there - LibreWolf, IceCat, PaleMoon - but they're mostly kinda...worse? I think the Chromium clones are doing it because it's well-supported by websites, idk if it's actually easier.
@prestontumber @eseilt @aeva My argument (which, I repeat, is just based on a hunch) is that if we had a good share of Firefox clones from day one, Firefox/Gecko might still be more relevant than it is today, alleviating the "poor support from websites" part.
The Firefox forks you mentioned are, by the way, a good start, but AFAIK they deviate much less from upstream Firefox (in UI/UX or functionality) than some of the Chromium forks do.
