Description Doran Moppert 2019-09-04 00:48:10 UTC 
Given a compromised sandboxed content process due to a separate vulnerability, it is possible to escape that sandbox by loading `accounts.firefox.com` in that process and forcing a log-in to a malicious Firefox Sync account. Preference settings that disable the sandbox are then synchronized to the local machine and the compromised browser would restart without the sandbox if a crash is triggered.
