I did a clean Windows 10 install and when I've installed Firefox again and logged in, I'm unable to sync or stay logged in. My profile icon at the top right has a yellow symbol and when I click the icon it says "Account Disconnected". Clicking again takes me to the sync page where it tells me to "sign in to reconnect", but every time I log in again, it does the same thing and leaves me unable to sync my data, meaning I can't restore all my plug-ins, bookmarks, and browser history. I've tried some of the fixes listed in the forum such as making a new profile or reloading the browser but nothing is working for me.
