I always try Firefox every 6 months or so but end up going back to a Chromium based browser after a few days. It's never anything major but for example this issue with the address bar suggesting the root domain instead of the pages I actually visit drives me nuts - https://www.reddit.com/r/firefox/comments/a2wz6x/firefox_add...

I'm glad they're continuing to improve the browser, maybe this update will be the one that convinces me to switch!
