Firefox currently blocks port 10080 to protect against a presumed security threat. Linksys routers use port 10080 to allow users to log in to the guest network so Firefox has rendered Guest Network logins to be unaccessable forcing router owner to allow "guests" to log in to the the primary lan and potentially cause issues with the very network they are trying to protect from outside issues. Firefox needs to provide a way for guests to log into the guest network within their software... particularly in the ios and android versions of the Firefox apps.
