About GL's JavaScript Firewall

The ultimate JavaScript firewall. Block all scripts by default and choose which websites you trust for a faster, safer, and cleaner browsing experience. Take back control of your browser with GL's JavaScript Firewall, a powerful extension that puts you in charge of which websites are allowed to run code. By adopting a "default-deny" policy, this firewall blocks all JavaScript from running on any website until you explicitly grant permission. This simple yet powerful approach dramatically improves your online experience in several key ways: - Boost Browsing Speed: Pages load significantly faster by preventing heavy, non-essential scripts from ever running. - Enhance Your Privacy: Instantly stop countless tracking scripts that monitor your behavior across the web. - Increase Security: Protect yourself from malicious scripts, malvertising, and certain types of cross-site scripting (XSS) attacks. - Reduce Distractions: Eliminate annoying pop-ups, auto-playing videos, and intrusive overlays that rely on JavaScript to function. Key Features: - Block by Default: All JavaScript is blocked by default for maximum security and privacy. - Simple Allow List: Easily add trusted domains or subdomains to your personal Allow List with a single click. - Dynamic Controls: The extension icon provides a simple popup to "Allow" or "Block" the current site instantly. - Temporary Pause: Need to disable the firewall for a bit? "Pause for this Tab" or "Pause until Browser Restarts" gives you flexible, temporary access without compromising your Allow List. This is a specially useful feature for sites that use third party JS scripts (Hosted in other domains). Other extensions would require you to approve every single different source of script and now you just have to approve (trust) the domain you are currently visiting (Pause for this Tab). - Lightweight & Efficient: Built using Chrome's modern declarativeNetRequest API, the firewall operates with maximum efficiency and minimal system impact, without ever reading page content. - Privacy-Focused: Your Allow List is stored securely on your device and synced across your browsers. We never collect or sell your data. Install GL's JavaScript Firewall today and experience a cleaner, faster, and more secure web, on your terms.
