Mozilla is not and never has been a browser company. They have always been a charity with a for profit arm that does a browser. However never has a browser been more than an after thought to any of the leadership.
Of course what the world really needs is a browser company and so we try to pretend Mozilla is that, but they are not. Support an alternative browser (I'm not aware of any though. There are browser skin companies but nobody making the hard parts of a browser)
I’m aware of at least two honest-to-goodness new browser projects:
There’s Servo, which used to be from Mozilla, but then they abandoned it. Now I believe it’s independent after a long period of dormancy.
There is also Ladybird, whose founder is a prolific and technically brilliant person but who is also, at minimum, a fascist sympathizer, in addition to being a supporter of white replacement theory and other racist ideas.
Neither project, last I checked, is really close to being a “daily driver.” But they’re both in active development, so maybe in the future they’ll become legit alternatives to the Google/Apple duopoly.
