BlockURL by BeatLink

BlockURL is a Firefox extension to block a specific URL or link. Unlike other blockers, it doesn't work on a domain or subdomain but a specific URL. This is mainly useful for blocking visited articles, videos, pages and other content

BlockURL uses a Python Flask Sync Server in order to store all of the URLs that are blocked as well as the text for the blocked page. This sync server is hosted on DockerHub at https://hub.docker.com/r/beatlink/blockurl

The source code and README documentation can be found at https://github.com/BeatLink/BlockURL
