Neat URL is a Firefox extension designed to enhance your web browsing experience by cleaning up URLs. This tool effectively removes unnecessary parameters, such as Google Analytics' UTM tags, from URLs to simplify links. Users can customize their URL cleaning preferences by adding specific rules that can apply globally or to specific domains. For example, one can set rules to eliminate parameters like 'utm_source' for every domain or restrict certain parameters to specific domains using a wildcard system. This flexibility allows for a more organized and cleaner browsing experience.

The extension also incorporates several improvements over its predecessor, Lean URL. Notable features include the ability to set your own URL parameters, compatibility with recent Firefox versions, and domain-specific blocked parameters. Additionally, Neat URL offers a customizable toolbar animation that can be adjusted or disabled according to user preferences. This extension is a free and effective solution for users looking to enhance how URLs are handled in their browser.
