no "Remember this decision" option
Build ID :
Mozilla/5.0 (WindowsNT 6.1; WOW64; rv:52.0) Gecko/20100101 Firefox/52.0
Steps to reproduce :
1. Open Firefox Beta 52.0b3 in a new profile
2. Then go to the following link : http://www.thegreatpotoo.com/webrtc-samples/src/content/peerconnection/dtmf/
3. In the webpage you would notice a "call" button
4. When you click the button, you would see the pop-up requesting for microphone permission
Actual Result : In the pop up there is no "Remember this decision" option as it is in the Nightly 54.0a1
Expected Result : There should have been a option for "Remember this decision".
The checkbox has been added in bug 1282768 which is riding the trains starting at v53, so it's in Aurora/Developer Edition right now. You can either use that or wait a little longer ;)
Also note that this is an insecure HTTP page, so you would not be able to permanently allow microphone access there anyway.
