This is part of the family-friendly browsing requests for a blocklist for childen. We want the service team to parse an incoming block list and deploy it on the server. We are currently planning on using this list: http://urlblacklist.com/?sec=download Let me know if you have any questions in regards to the format.
Ryan, do you need us to help create a repo for this list, similar to the shavar-prod-lists repo used for tracking protection? The Fennec team will maintain this list, similarly to how Javaun and Francois maintain the TP list.
No longer needed since that feature will no longer rely on a blacklist.
