Excellent browser and love all it's features; yes I have used others; Vivaldi, Safari, Chrome, Opera; all have something to offer, but Firefox hit me with a brick, after I learned how to sync my account, so I will lose nothing. The 'Generic forks; Cliqz, Waterfox, Pale Moon and others do not present the needed security updates and new versions as quick as Firefox. Firefox is at 73.01, and is rock solid. I do not have a cell phone, so my data is synced with Firefox. I read the complaints by choice, reviews; that will not stand in my way. If you are not a fan of FF, please use another browser that floats your boat; that is using a "moral compass"

This version is incredibly fast! As much for launching the application as for loading web pages. In addition, there are a ton of additions to customize the browser.

Many, many years of using Firefox browser in Windows and Mac machines. Now I have a strange problem in my iMac Catalina machine with Firefox 81.0.2 (64-bit). I am not able to sign into my user account in some web seller's page and not able to open their responses to me. Firefox 81.0.2 just complains that I should allow cookies, which I do. By contrast I am able perform those tasks in my MacBook machine running Mojave and Firefox browser 81.0.1 (64-bit) having the same cookie settings.

Slooooowwww, Very, very, very, slow .... Lots of "page timed out" / "connection timed out" / "Resend" messages constantly popping up. Why? Microsoft Edge and Epic web browsers are doing this when used on the same computer with the same internet connection. I even tried disabling my add-ons to see if that made a difference, but sadly, no ....

It took awhile to learn all of the features and now I love it. The debugger is better, and the sync is better. And the privacy is better. Keep up the good work.
