It sounds like a management issue. They keep frolicking around and not listening to the userbase. There is no reason other than management that Mozilla couldn't be a profitable and sustainable company. They create some half baked thing no one asked for and then kill it off.

And then SimpleLogin comes, as just one example, and succeeds. Mozilla obviously messed up all their efforts, for one reason or another.

That's why you make enterprise products. Companies will continue to pay for services they don't even use for years because nobody knows what it is or what it does.
