Using either of those browsers when I try to log in via the "Sign in through steam" button, it takes me to steam's website, I hit sign in, and then it takes me back to steamrep but nothing seems to change. I also can't send messages or anything via it. When I click Send Message, it asks "Open Steam Client Bootstrapper?" but if I click Open Steam Client Bootstrapper, nothing happens. I assume that's because I can't sign in? I have been unable to find anyone else having these issues.
