Logged in with Waterfox now can't log out?

I logged into my GitHub account using Waterfox, and now I can’t get the dropdown list when I click the user icon in the upper right corner so that I can log out. In other browsers it does not show me logged in, and I can log in and log out repeatedly in another browser like Firefox, but it doesn’t show me as logging out in Waterfox. How do I get logged out in Waterfox? Thanks for any help anyone can give.

Hi @SteveH66 and welcome to the forum!

Officially, Waterfox is not supported by GitHub.

If you’d like to terminate the session you started in Waterfox, log in on a different (supported) browser, navigate to [Account Security](Sign in to GitHub · GitHub, scroll down to Sessions and revoke that session.
