 +media.ffvpx.enabled = true

 +====== Using Telavox web based SIP phone with FF ======
 +===== Need to spoof the user-agent to include "Chrome" =====
 +
 +Install [[https://addons.mozilla.org/en-US/firefox/addon/user-agent-string-switcher/|User-Agent switcher]] \\
 +
 +Then add this to the "Custom Mode" configuration
 +
 +<code ecmascript>
 +{
 +  "app.telavox.com": "${userAgent} Chrome"
 +}
 +</code>
 +
 +===== Now you also need to manually enable accepting calls =====
 +This is due to [[https://stackoverflow.com/questions/59131286/how-to-check-if-the-permission-to-access-microphone-has-been-rejected-by-the-use|microphone permisssion not queryable]]
 +
 +First make sure that you have allowed persistent access to microphone. \\
 +Then add the value registerSoftphone:"true" to the "Local Storage" for https://app.telavox.com
 +
 +If you then go to "Settings | Phone and audio" you should see that "Receive incoming calls" is now enabled.
