I use FF to browse / login to the forums. If you have a version 51 or higher, it warns that the login is insecure (not https:// ). I don't know what would be required to secure at least the login page, but it is probably a good idea to do so. If there is a secure login to the forum, please feel free to post it, as I wasn't able to find one.
Here is a link to what FF shows when you go to log in .
