Mozilla is an ad company now.
Apple is an ad company.
Some times Google just decides you can not pass no matter what you do, but you still get the captchas.
Nowadays Firefox is just a poor Chrome knockoff with no distinguishing features. As a casual user who switches but is unaware of add-ons/etc, Firefox gives you nothing, so why would you switch?
Firefox can reinvent itself and regain marketshare by shipping actually useful features like built-in ad & distraction blocking, but chooses not to.
but around 2010-ish, chrome got way better and superior in every way. even I cant ignore that and switch to chrome
until they recently nerf adblock and I use dual browser, good thing firefox is still there. but I cant say the same for 20 years in the future
