About

This extension lets you block specific JavaScript files across all websites to keep your browsing environment clean and predictable ⚙️

You can add any script URL you want to block, such as example.com/min.js. The extension stores these entries locally and uses the Declarative Net Request API to prevent matching scripts from loading on any site. This helps you avoid unwanted libraries, trackers, analytics scripts, or any external JavaScript you prefer not to run 🛡️

Your list is fully under your control. You can add or remove URLs, temporarily enable or disable individual rules, or toggle the entire extension on or off at any time. You can also export your rule list or import one with a single click, which makes backup and sharing simple 📦

No data is collected, and all configuration stays on your device.
Free and open source, ideal for users who want more control without relying on predefined blocklists.
