RequestPolicy is an open-source Firefox extension developed by Justin Samuel, designed to give users control over when web pages can make cross-site requests. It is not a traditional enterprise gateway or cloud security product, but a privacy and security tool that runs inside Mozilla/Firefox. The text indicates that it is licensed under GPL v3 and positioned as free software.
In terms of protection, RequestPolicy’s core function is a default-deny policy for cross-site requests: requests from the current page to third-party domains are blocked by default, and users can then create whitelists as needed. It can cover the loading of third-party images, JavaScript, stylesheets, and other content, and can also block cross-site redirects, page prefetching, and DNS prefetch-related behavior. For site classification, it distinguishes third parties by registered domain by default, while allowing finer granularity down to full domains, or even combinations of protocol, domain, and port.
For usability, it provides status feedback through a flag icon in the browser: when the current page has blocked requests, the icon turns red. Blocked cross-site images are shown with a red flag and border, and hovering over them reveals the source domain. Clicking the icon lets users see which target domains have been allowed or blocked, and permit specific cross-site requests. This interaction model is intuitive, but the default blocking policy can cause some pages to render incorrectly or lose functionality, so ordinary users will face a learning curve.
On pricing, the text only states that it is GPL v3 free software, with no information about commercial subscriptions, enterprise editions, or paid support. Support channels include documentation, FAQ, tutorials, GitHub, a Bug & Feature Tracker, discussion lists, and a contact page, indicating a community-oriented support model. The text also suggests that the original project information is relatively old and notes that development continues on the newer RequestPolicy Continued website.
Its advantages are that it is free and open source, has a clear policy model, offers fine-grained control over cross-site requests, and can complement NoScript, making it especially useful for reducing third-party tracking and CSRF-related risks. Its drawbacks are that it only targets Firefox/Mozilla, with the text explicitly stating there is no Chrome version; websites can detect that the user is using the extension; whitelist and other configuration files may remain after uninstalling; and there is no information about enterprise centralized management, compliance certifications, or SIEM integration. It is better suited to privacy-conscious individual users, security researchers, and advanced Firefox users than to enterprises that need centralized policy deployment and audit reporting.
The crawled text does not provide information on access from mainland China, payment, or localized services, so its availability in China is unknown. Since it is a browser extension and open-source project, actual installation may depend on access to Firefox add-on channels, GitHub, or the new project website. Alternatives could include browser security extensions such as NoScript, but the text emphasizes that NoScript and RequestPolicy are complementary rather than direct substitutes.
