    Project mention: uBlock Origin Forcefully Removed by Chrome | news.ycombinator.com | 2025-03-04

    Firefox is a less bad option, even with the recent stupid policy changes they've made.

    Or there are a bunch of [other options that care about privacy](https://privacytests.org/), Brave, Librewolf, Arc, Zen, Orion (Kagi's thing). I tried Orion for a couple days, but it started crashing randomly and felt unstable and slowed down after real-world use (3-4 windows, many many tabs).

    I really wish there was more competition here from the smaller, privacy focused players...but the reality is building a browser is insanely difficult for the modern web.
