I have a website that has the user repeatedly record audio clips for speech recognition/evaluation purposes. On all other major browsers the user is prompted once for permission to use the microphone, and then is able to proceed through the rest of the process without any problem. On Firefox for Android however, the user is prompted if they will give permission to use the microphone between each recording session. For context, each recording is only a few seconds long and there can be 30-60 of them. Also, there is no 'remember my preference' checkbox on the permission window that pops-up. Could anyone please tell us how can we resolve this issue.
