  - iframe sandbox rules did not apply to XSLT stylesheets.

  - Use-after-free in file picker dialog.

  - Firefox could be coaxed into going into fullscreen mode without notification or warning.

  - Opportunistic Encryption in HTTP2 could be used to bypass the Same-Origin-Policy on services hosted on other ports.

  - Permission Prompt could be overlaid, resulting in user confusion and potential spoofing.

  - Web Extensions could access pre-redirect URL when their context menu was triggered by a user.

  - Javascript alert box could have been spoofed onto an arbitrary domain.

  - Download Protections were bypassed by .inetloc files on Mac OS X.

  - 'Copy Image Link' context menu action could have been abused to see authentication tokens.

  - URL Parsing may incorrectly parse internationalized domains.

  - Memory safety bugs fixed in Firefox 94 and Firefox ESR 91.3.");
