After upgrading to Firefox 19 I tried to use my microphone but no one can hear me. I went to control panel and sounds and tried to raise the level but it has not solved the problem. I tried various applications that facilitate a test recording (skype and blackboard collaborate) and none of these tests are playing back any sound from my recording. The microphone was working fine before the upgrade and sound could be recorded from 10 feet away.

Firefox File Menu > EXIT.

Restart your system and give a try..


The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: This will cause you to lose any Extensions, Open websites, and some Preferences.

To Reset Firefox do the following:

  1. Go to Firefox > Help > Troubleshooting Information.
  2. Click the "Reset Firefox" button.
  3. Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
  4. Firefox will open with all factory defaults applied.


Further information can be found in the Refresh Firefox - reset add-ons and settings article.

Thanks. I tried this procedure and restarted my computer but I am still getting the message 'audio system error cannot read from microphone'. The wireless mouse still has no function.
