Application Guard Extension

View untrusted websites in a separate Microsoft Edge browsing window to help protect your device from advanced threats.
Application Guard Extension is a Firefox add-on developed by Microsoft. It aims to protect the device from advanced threats by directing untrusted websites to a separate, isolated version of Microsoft Edge. This safeguard ensures that any potential malicious sites remain within a secure container, thereby preserving the security of your device. This extension is compatible with latest Windows 10 versions (Professional, Enterprise, Education); however, automatic redirection of untrusted sites is not available in an unmanaged environment.

Nem működik a Firefox-ban, nem tudom miért nem office-ban igen, Chrome-ban igen, Firefox-ban nem! "Nem kompatibilis eszköz" -t ír! A "böngészőjét szervezete felügyeli" jelen van az edge-ben és Chrome-ban is nem tudom az okát (win11).
