Features: - Clicking the popup icons allows to enable or disable First Party Isolation on the fly. - Allows to remember previous state of the FPI, or enable/disable it by defeault. - Domain whitelisting (experimental)
Please note! Domain whitelisting is purely experimental. Firefox's FPI setting is global, so at this point there's no guarantee it can be triggered on/off fast enough when switching tabs. It can also break various sites that update the content in the background.
