No Audio after update to Quantum
Ever since I updated to Quantum, I keep having to use chrome. I have no audio in firefox now. Every other program works but not firefox. Videos play, but no audio. The videos are not muted, the tabs are not muted, the channel mixer is not muted, deactivating all plug ins/extensions (and restarting) have not helped. WTF
Windows 10 x64 via remote desktop connection.

uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files and C:\Program Files(x86) Then restart system. Then run Windows Disk Cleanup. (Note: This should be Pinned and run Weekly, If never done below expect 10's of gig's) Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved. But you should make a back up before you do : https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles
