I've been using Firefox as my main browser for most of 2019. So far the *only* times the experience has been noticeably worse are on Google properties.— Richard Feldman (@rtfeldman) June 23, 2019
* Gmail, Calendar, and Slides are so slow as to be barely usable in FF.
* Google's reCAPTCHA makes me click lots of images now.
Gmail itself sucks in both browsers, have to use gmail notifier in Firefox
