On the contrary,
I have ALWAYS been a devoted FF user, going way back, and not by choice, but by need, simply because there never really was, or is, any other truly free/opensource browser out there, period. !
Chromium? -well that’s only there for google-chrome closed/prop devs to steal new idea’s for Google’ greedy tie-in empire -so no, I don’t even count chromium as anything but a leeching-browser.
Every other browser has learned/stole everything they know, from the grandaddy of them all -mozilla.
Lol, Mozilla/FF never left the game, they’re simply fighting against ALL these capitalista’'s baby.!
So, if the free/opensource FF ever goes, then so will I, well maybe not, since there are still many other free/opensource (alternative) browsers, like pale-moon, …, -that are of course based upon FF.
