RequestIsolation is an experimental security extension for Chrome that aims to enhance security by isolating requests to specific domains. This feature allows these domains to be accessed solely through the extension's popup, effectively preventing various security threats such as URL-based reflected XSS, Timing attacks via the opener, CSRF, postMessage attacks, and clickjacking attacks.

While the utility of RequestIsolation may not immediately appeal to the average user, its focus on bolstering security measures within the browsing experience is noteworthy. This extension serves as a proactive measure against potential vulnerabilities, offering an additional layer of protection for users seeking to safeguard their online activities.
