“Important News”

I’ve just started using Firefox ( literally one day ago) and I’m not sure about how it’s meant to work. This is driving me mental. When I open the Firefox browser on my mac I get this pop up window every time “Important News” This installation of Firefox has a new profile . It does not share bookmarks, passwords, and user preferences with other installations of Firefox on this computer. -Then I’m asked to sign in to my account . -Then a second window appears and I’m asked to fill out my password to continue to Firefox Sync. -It asks if I want to save this log in which I say yes to but I’m always having to fill out my log in info anyway. -A third window appears which after the first few times I now ignore as I completed this task on the first time I set up Firefox- so now I just close this window. This one says “This Firefox is connected. Send Firefox directly to your smart phone and sign up to complete set-up.” Asking me to fill in my mobile number. **All the above EVERY time I click on the Firefox browser. **Consequently I keep getting these emails notifying me of a new sign up. **How do I opt out of the constant “New sign-in to Firefox Lockwise “ emails? **Can you not use the browser without having to go through these multiple windows asking you to sign in ?
