Because it is a bloatware. Like, what is the point of using Firefox? It’s faster? It was never because of speed. Less RAM usage? No. It was because of privacy. Peoples started hating on Chrome because Google became evil. Then they went after adblockers. Google search became bloated with garbage results, DDG became a better alternative, also marketed as privacy-focused.
It just happens to be that out of all other web browsers, there were no better alternatives, and Firefox seemed the best option at that time. Opera was a spyware. Brave was still fresh. Actually, Brendan Eich, the founder of Brave who also founded Mozilla and created JavaScript, was called out for making an anti-LGBTQ donation, so many people hesitated using Brave when it released. Needless to say, anything Microsoft was hated with a passion.
That’s why people need to keep reinventing the wheel.



Thing is, I have configured my Firefox to be as “private” as possible. It can also backfire, because corps can fingerprint you based on your browser’s preferences. So, when I am saying Firefox is bloatware is because it is out-of-the-box. You can spend hours tinkering with it, but the average person won’t bother doing that, so Mozilla would force them to be part of their ecosystem through all those syncs, branding, AI, no actual strict privacy by default, etc. That’s what I call bloat, that on-boarding experience with terrible UI changes.
