I have tried installing the C2 Password extension in Orion v1.0 on MacOS and it seems to be loading fine -- in that the extension icon shows up and offers its options -- but if I try to log into my account, it just opens a blank page and will not continue. I have tried the Mac store version of the extension ( https://apps.apple.com/us/app/c2-password/id1566336292 ), which is the one I use without issue in Safari, and I also tried the Chrome and Firefox versions of the extension just to see if that would work but they failed the same way.
If I use the Create Account option instead of Sign In, it will take to me to a C2 page where I can sign in, and it goes through that process normally and I can access my password data from within that page, but it does not reflect back to the extension itself which remains logged out.

It should bring up a loging box and then allow me to access my logins and offer filling on web pages but it remains logged out. It does show the C2 icon in login/password fields it finds on a page, but it continues to prompt me to log in instead of showing the actual data.
The extension functions fine when using Safari.
