I switched to Firefox last year when talks of chromium manifest V3 First started popping up. I had used Firefox many years ago when Chrome was first coming out. I was blown away at how well it worked compared to old Firefox, plus how easy they made it to switch. I even changed my phone browser and my desktop browser ties in with it seamlessly. Very happy with the switch and I wish I had switched earlier.
Now, I just wish I could use it at work. Not sure how I'm going to block ads on my work browser.
