I set up a new Pop!_OS 20.04 on a PC. I signed into my firefox account to get some bookmarks to help me set up the PC. I signed out of firefox so that I could set up a new firefox account for this PC. I am then unable to create a new account. I am always greeted with a sign-in prompt. There is no way for me to get an account set up form. I tried starting in safe mode. I tried purging firefox and deleting the .mozilla directory. When I go to turn on sync it asks me to sign in only. When I go to https://www.mozilla.org and click on "Get a Firefox Account", it sends me to the sign in page. If I click to "Use a different account" is goes to a sign in page again. If I enter an email and password it tells me "Primary account email required for sign-in" Any help would be appreciated.
