I've been seeing a lot of people hate and uninstall Brave. Why? It's not like they're tracking us or doing anything else shady. If so, what's the privacy alternative?
I am a very, very long time Firefox user. Brave probably has a case for getting Chrome users to consider switching, but I've never encountered any compelling reason to consider switching from Firefox to Brave.
If a site breaks because you're using ff, the web developer behind it is clearly a fucking idiot. If it works in chrome it's going to work in FF, unless you've done something extraordinarily stupid.
A ton of websites? I block 3.5 million domains through DNS and run uBlock Origin, Privacy Badger and some other anti-tracking bits and pieces, and I've only ever had problems with a small handful of sites, which were almost all resolved by temporarily unblocking something. I have had to hop over to a Chromium-based browser only once in recent months, for one particularly badly implemented website. Where are you seeing this "ton" of sites that break? My experience has been quite different.
I find it's just fine to use Firefox and hop over to Brave about once a year when something doesn't work.
