true, I only wish Firefox could bridge some of the performance gap, but frankly, it's pretty fine as it is - Firefox Sync is much better than Safari/Chrome options, you can close tabs remotely, sending tabs is instantaneous and never fails (Chrome IME was flaky) - as the article mentions, a lot of mobile addons, including Stylus and the *Monkey userscript addons, I have cloud sync set up for both and it's nice to have userscripts running on all platforms - Tree Style Tabs is still the best UI for managing tabs in any browser I've used - browser UI customization via userChrome.css file, and user.js for persistent about:config flags, every time you set up a new Chrome profile, have to set up flags manually - it's fast (enough), ironically I switched from Chrome after I started have inexplicable slowdowns that I couldn't solve by disabling extensions or a new profile, since the Manifest V2 moment was upon us, I took the opportunity to give Firefox a try again
