First of all, Lunduke… has very funny opinions on things, as his politics massively shifted in the past 4-5 years, as someone who used to follow his rants before he became a rightwinger. His interview at Chris Titus channel was also a bit unhinged, and Titus protected him by hushing him a fair bit.
Secondly, unique IDs are only a thing when you download the Firefox online installer stub from their website. If you download the offline installer from their website or from any decent Windows software site (Majorgeeks, Filehorse et al), this is not a problem. Also, this is not at all a problem on Linux, since the software installation method is fully centralised.
What I will criticise is CEOs have been leeches at Mozilla. Emily Baker has been an absolute leech, and there is no denying about it. The new CEO is also a leech. But that has not affected Firefox. It may, however, affect Firefox as the developer money is snatched by CEOs. What has affected Firefox is how the world has shaped up, and people are okay with having less privacy because western elites have helped create that ecosystem for masses to cuck themselves. I am not going to honk trumpets for their inclusive politics like a liberal, but it has allowed to distance them from clowns like Brendan Eich, which has been fairly helpful.
Also your point about UGC using uBO is nonsense. Manifest V3 simply disallows the full capabilities of uBO on Chromium browsers due to its hard cap on memory limits. Raymond Hill has a lot of words to say about it. uBO Lite is about as good as uBO easy mode but even lighter, and you cannot block selective domains or scripts at all. Not to mention, uBO on Firefox allows importing extra filter text files, which is not an option on Chromium browsers.
Firefox has customisable user.js and userchrome.css, so the former allows implementing Arkenfox’s configuration and such things.
I’m NOT sorry for the trouble and mental break down I may have caused by the sudden realization that Firefox is as good and private after all, if you can put in a little work. You may cry, whine and bang your head about it. Your disinformation cope attempt has failed.
