RequestPolicy is an open source add-on for the Firefox web browser that helps protect against malicious websites by preventing cross-site requests (XSRF) and other types of malicious activities. The add-on allows users to control which websites may request content from other sites, as well as which websites are allowed to set cookies. Additionally, RequestPolicy can be used to protect against clickjacking attempts and prevent tracking data from being sent to third-parties. The add-on also allows users to whitelist specific domains, allowing them to access content from the domain while still blocking other requests. RequestPolicy is an excellent tool to help protect your privacy and security while browsing the web.
