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. This vulnerability affects
Firefox ESR < 60.9, Firefox ESR < 68.1, and Firefox < 69.
