SafeSearch Enforcer од Mauro Mascarenhas

This extension aims to enforce engines to proccess the search queries in a safer mode, even if the configuration is manually set, it will be restored to the strictiest role.

Unfortunately, other content filtering extensions do not provide this feature, and alternative blocking methods like DNS and Proxy also do not filter search results. Therefore this extension should be used as a complement for child protection suites.

This extension supports five known search engines:

• Google : Domains and subdomains.
• Bing : Domains and subdomains.
• Yahoo : Domains and subdomains.
• Yandex : Domains and subdomains.
• DuckDuckGo : Domains and subdomains.
• Reddit : Search results, sections, posts and profiles.
• Imgur : Filters NSFW content (linked to Reddit).

It also supports site blocking (through block list rules), accordingly to the user's preferences.
