Firefox 55.0.3 Windows 7 has no sound
Updated to 55.0.3 from 55.0.2 on Windows 7 and yall messed up. I have uninstalled and reinstalled my sound driver, even uninstalled and reinstalled Firefox and have sound EVERYWHERE else except the browser my school demands we use. You really need to fix this issue. In the meantime, I'll be downgrading back to 55.0.2 or before until this is fixed. Also, please stop forcing updates on us until ALL bugs (especially important ones like this) have been addressed.
