Le site requestpolicy.com est-il sûr ?

RequestPolicy is an add-on for Firefox and compatible web browsers that offers an unprecedented control over which cross-site requests your browser makes. Typically a browser loads resources from multiple sites when defined in an html page. With RequestPolicy, you can prevent the browser from making such request. This will break a lot of sites, especially sites that links images from other sites, but it helps you control which site your browser "talks" to, which means you can effectively prevent ads, trackers, and malicious sites from ever loading. It may be a daunting task to learn usage at first, but once you get the gist and develop a base whitelist, then the reward is more than the troubles you will take.
