RaTasha Tillery-Smith 2023-08-02 13:11:08 UTC Doc Text The Mozilla Foundation Security Advisory describes this flaw as:

The Firefox updater created a directory writable by non-privileged users. When uninstalling Firefox, any files in that directory would be recursively deleted with the permissions of the uninstalling user account. This could be combined with creation of a junction (a form of symbolic link) to allow arbitrary file deletion controlled by the non-privileged user.

*This bug only affects Firefox on Windows. Other operating systems are unaffected.*
