Currently there is a "Help/Report Deceptive Site" there also needs to be a "Help/Report Non loading site" this needs to highlight security settings, and issues. i.e. Ikea Canada, if you have 'Settings/Privacy & Security/Strict' you are not able to login to the site, with '/Standard' you are. This feedback could allow the Mozilla devs to address 'key sites' or a add a new function that highlights the issue to the user, so they could add an exception for the site while maintaining /Strict for other sites.
