The Atlassian Confluence "Audio Briefings" icon is consistently greyed out using the Firefox web browser (my browser of choice). How can this be enabled? This is not an issue using the Chrome and Safari web browsers on the same content. I have verified Autoplay, Microphone and Speaker settings and ensured the domain has been added to the list of exceptions to the default (which is more restrictive). Hardware and WebGL are both enabled as well. I would think Firefox would want to ensure the browser is compatible with major business applications such as those by Atlassian.
