CVE-2018-5152 is fixed in 4 products on 1 platform, first by firefox 60.0+build2-0ubuntu1, released May 10, 2018. It is not reported as exploited. Patch Radar priority: Routine.
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.
