HEADLINE: Child friendly (ad blocker, content filter)
DESCRIPTION: For my son's first computer, I picked Lubuntu and spent days making it "internet ready". I installed Dansguardian + Privoxy, then added uBlock Origin to Chrome, then added OpenDNS to my home router. It was a lot of searching online and trial & error but worth it. From time to time, I check websites he visited and what got blocked (grepping logs) and adjust accordingly. One problem with this is updates are blocked so I must disable proxy manually every time I update.
Please consider making something like this available out-of-the-box. Something that can be enabled/disabled with a few clicks. Also, a simple way to review history and adjust settings. It would make Ubuntu an excellent choice out-of-the-box for all kids. Thank you for asking.
