I installed it, and tried to connect to a site I already had an account on. When I click on the email address field to of my login, I cannot type anything anymore. I see only the Firefox RElay icon, even my password vault icon disapeared. I have no other choice but using Firefox relay, so I cannot even enter the email address I signed in with to change the address to a generated alias. I had to go to preference to unclick the option "Show relay Icon in email fields on website". Not practical at all.
