I tried migrating from Chrome to Firefox with the recent developments. The user experience of Mozilla could be better, imo.
After not liking Firefox, I tried four more browsers: Orion, Arch, Brave, and Vivaldi. I finally landed on using Brave.
After you turn off everything related to crypto, it becomes a great and user-friendly browser with adversarial interoperability with Chrome. It's the only browser with an actual chance of beating Chrome by convincing its users to migrate.
I'm hoping they can continue maintaining the Chromium fork (it's an actual fork, by the way), as it'll get harder and harder as it diverges more and more.
