Kiosk Page Blocker nga GlitchyPie169

Block or only allow pages that meet customisable URL filters to stop users from breaking out of predefined pages on your kiosk.

Filters support filtering by protocol, domain, path, and even query string. Filters even support regular expressions allowing for a great amount of flexibility to suit your filter needs.

Not only can you define filters 'locally', filters may be defined via policies as well, such as in policies.json.

There are also inbuilt options to block requests that return "content-disposition: attachment" headers, helping to prevent file downloads, and can also block pages that don't return a standard text/html MIME type, further preventing pages from potentially breaking out of the intended view.

NB: This addon is designed to compliment Firefox's in built kiosk mode and a well configured policies.json file, it is not intended to be a standalone solution. It does not block popups on it's own nor can it fully prevent downloads if the site does something that bypasses the configured filters.
