My workplace uses a captive portal to enable internet access, up until now I have not had any problem when login in with Firefox. However, since this morning, a message started appearing when I try to log in (see attached picture), I click on open network login page but it opens the exact same page on another tab, so I have had to switch to another browser for authentication. The other browser alerts me of a bad certificate when I try to log in but it doesn't give me more problems. Suspecting a problem with the certificate I hit the advanced button on the picture and clicked add exception, but nothing happened.

Is there some kind of bug with this page? Can I add the exception in some other way?

Try to rename/remove SiteSecurityServiceState.txt in the profile folder or edit the file and remove lines that refer to this domain.

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.
