Browser Fingerprint Protector

This extension is no longer maintained or recommended, as I don't believe this battle can be won. To try to protect against fingerprinting attacks, consider using Tor Browser or similar projects.

Available in Firefox Add-ons and Chrome Web Store.

How it works

The extension protects the information in window.navigator and HTTP request headers to complicate browser fingerprinting.

• Completely hides mimeTypes and plugins.
• Pretends that you only have English US language.
• Pretends that you use Windows 10.

How to validate that it works

• whoer.net is a good way to see what browser is leaking. Ignore the "anonymity percentage", focus on the information that it is able to retrieve, such as languages, user agent, plugins, etc.
• Most Common User Agents is a website that shows the current most common user agent. It is expected that with this extension your browser is listed among the first few entries in the table.

Other useful extensions to protect your privacy

• HTTPS Everywhere
• uBlock Origin
