* GPU acceleration doesn't work properly with Firefox/Linux (Dell G5 SE, Ryzen 4800H). Some sites I use daily, such as Google Maps, are painfully slow/laggy on Firefox.
* There's something about the Firefox's scrolling behaviour that I find really annoying.
* It works well across all platforms (Firefox on Android wasn't great last time I checked).
* It's the most tested browser. Many websites don't bother to test with Firefox.
* Chrome has the richest extension ecosystem.
* Some of the alternatives, such as Brave are not as trustworthy. Security is a bigger concern than privacy for me. Google has one of the best security track records.
* I'm heavily invested in the Google ecosystem, and I use dozens of their products. There's always a switching cost involved. Just changing the browser has a negligable effect on privacy if I'm constantly using the other Google services.
* Personally had overall an overwhelmingly positive experience over the last 15+ years I've been in the Google ecosystem. Google hasn't done anything to betray my trust so far.
