Does this matter?

Lower severity and a low EPSS score (0.90%). Track it; it rarely justifies an emergency change on its own.

Description

The "mozAddonManager" allows for the installation of extensions from the CDN for addons.mozilla.org, a publicly accessible site. This could allow malicious extensions to install additional extensions from the CDN in combination with an XSS attack on Mozilla AMO sites. This vulnerability affects Firefox < 51.
