What to do when a website has TLS issues with #Firefox on #Fedora, but works flawlessly with Firefox on Windows and #Chromium on Fedora? It also has this strange behavior that doesn't even let me bypass the problem temporarily... #WebBrowsers #WebSecurity #HTTPS

@steko ? What site?

@snoot work webmail (no way to reproduce the issue without a valid password). On #Fedora both #Firefox and #Epiphany/Web have the same behavior, while Chromium works perfectly. I don't even know how to troubleshoot this situation, I'm stuck with this vague error message

@steko Hmm. without any more information than that, I'd guess that something after the authentication step redirects to something that doesn't match the TLS cert, as part of SSO or something. That's so odd, usually stuff works for me on FF on Fedora that *doesn't* work elsewhere. 🤔

@snoot exactly my expectation, too. I tried launching Firefox from the command line to obtain more detailed output, to no avail. Perhaps I should try with curl or Python requests to look at the specific error?
