WebExtensions with the appropriate permissions can attach content scripts
to Mozilla sites such as accounts.firefox.com and listen to network traffic
to the site through the “webRequest” API. For example, this allows for the
interception of username and an encrypted password during login to Firefox
Accounts. This issue does not expose synchronization traffic directly and
is limited to the process of user login to the website and the data
displayed to the user once logged in. This vulnerability affects Firefox <
60.
