When I see a message to update, I always do it immediately. A few weeks ago during an update the browser disappeared and wouldn't launch. I had no option but to uninstall with Revo Uninstaller Pro. When I installed again, I signed in and immediately selected sync and all my bookmarks were recovered but also Chrome bookmarks which I want to keep separately. No complaint, I just deleted all those Chrome bookmarks. Had to install all my Browser extensions. I have whitelisted a few websites to save cookies from those special websites like online Banking and got an auto popup message "You are using an untrusted browser" I had to use my phone to get a code from the Bank to continue. I use Biometrics to log into my Bank accounts and also many other websites I have installed on my phone. Then I got another message and email from the Banks verifying I have a Trusted Browser. Firefox is my default browser on my phone and my Laptop and always will be. Thanks for allowing me to write this message. I want to confirm this is not a complaint.
