Microsoft Edge was there but disappeared, but I can hear sound from Edge browser. I can hear system sounds and my speakers are working fine. But still no sound in Firefox. I have cleared the cache and cookies but still nothing. I have been using Firefox ever since it came out and would like to continue using the browser.
