Mozilla Launches 'Firefox Private Network' VPN Service as a Browser Extension https://thehackernews.com/2019/09/firefox-privacy-vpn-service.html
They destroyed customization in Firefox (by forcing the “new”, very limited WebExtensions), which was the prime reason for most people to use it to begin with;
Installed AddOns in Firefox forcibly in user’s browsers without their consent (you can read about the Looking Glass debacle for an instance of this). Maybe you can also remember that one time they broke all addons in existence by “forgetting” to update their signing keys;
Firefox by default sends out a metric shitton of metrics all the time which can uniquely identify users (I have 97 configuration changes to alter this, but you can’t really expect your average user to know these, and I don’t think anyone that is in favour of user privacy should even set this as a default).
Now, I don’t think there are better alternatives out there in the browser field (though ungoogled-chromium actually seems to be more privacy-friendly by default, I haven’t actually tried it yet), but having blind faith in Mozilla seems like a very silly thing to do in any case.
