Firefox cann't use microphone in my android 5.1 device. But a camera work perfectly (after confirm allow in a pop-up with asking "if you want to share your device’s camera and microphone with that site.") FireFox detect microfone as "default input device" but it doesn"t work. In a special sites that can test a work of the microphone, drop down list of the detected device (in the Firefox) contains only one item "default input device" and microphone doesn't work. In other browsers (Chrome), вesides this "default input device" that drop down also contains other items and microphone work perfectly I need to use microphone in Firefox for web version of a messenger that doesn't support in ohter browsers and apk on this android device
