One man's "useless UI redesigns" is another man's feature.
Every person I talk to has a completely different idea of what Mozilla should be doing. Keep pocket, or pocket is stupid, or pocket is the second coming of Christ, or the VPN is stupid, or the VPN is a revenue stream not dependent on Google, or whatever fucking bullshit.
Firefox does not "suck" - this is a legitimate psyop. It has all the features of Chrome minus the horrendous privacy violations. It has all the performance of Chrome, too.
I mean, what are we missing? Web USB? Give me a fucking break.
If you really, really need Web USB then fine - use Google Chrome. You win. 99.99% of people I've ever talked to don't even know what Web USB is, let alone do they rely on it.
