User Agent Switcher

User Agent Switcher and Manager operates locally in your browser, offering robust control over your digital signature – a key component websites use for identification and tracking. By altering your User-Agent (UA) string, this extension helps **reduce susceptibility to browser fingerprinting** and can **enhance online anonymity**. It comprehensively spoofs your identity by modifying not only the main UA string but also related JavaScript navigator properties like `appVersion`, `platform`, `vendor`, and `oscpu`. Gain **fine-grained control**: set unique UAs per website or tab, and **randomize User-Agent strings** to obscure browsing patterns. Advanced users can leverage custom UAs, JSON-based rules, and domain whitelisting/blacklisting. It supports incognito mode (user-enabled) and Firefox Containers for distinct UA profiles. As an **open-source tool (MIT License)**, its code is available for review, ensuring transparency. While it significantly bolsters privacy, use valid UAs to avoid site access issues. For optimal protection, complement it with browser-level UA settings; this extension will then manage detailed navigator properties for a consistent, **less trackable online presence**.
