My first attempt to load a website in a TOR tab following waiting out an unusually slow connection (acknowledged by BRAVE in an on-screen notification) resulted in its reporting a well-known secure website (Protonmail) as ‘not secure’.
I assumed it was a glitch and opened a second TOR window. This time Protonmail loaded without a problem.
Just reporting it. Bug? (I don’t know.)
