WebAPI/Security/FMRadioAPI
From MozillaWiki
WebFM API
Brief purpose of API: FM radio feature.
General Use Cases: Turn on/off the radio, change frequency, check status of various radio features Inherent threats: annoyance, drain the battery
Threat severity: Low
General notes: Multiple apps/pages can try to modify radio settings at the same time with the most recent action taking effect. Turning on the radio causes the audio stream to be played - there is no access to the stream data
