COMA Secure is a free browser extension for Chrome that enhances user security by blocking unwanted pop-ups, pop-unders, and malicious redirects. This tool is designed to maintain a smooth browsing experience while actively preventing navigation hijacking attempts that can disrupt or compromise user safety. Its primary focus is to allow legitimate website functionality while safeguarding against aggressive navigation mechanisms that may lead to unwanted content or phishing attempts.

Key features include the ability to block unwanted pop-ups and forced external redirects, ensuring that only user-selected domains are protected. Notably, COMA Secure does not interfere with legitimate ads or site content, which helps preserve the user experience. The extension operates by applying a security layer within the webpage context, detecting suspicious activities in real time, while also ensuring user privacy by not collecting personal data or tracking browsing habits.
