No Sound Vista Users: Do you see the Firefox application in the Mixer if you visit a website that has sound? You can click the Volume icon on the Windows Taskbar near the clock and click the Mixer link at the bottom to open the mixer.

Other Issues: to correct security/stability issues

Update Java: your version 1.6.0; current version (important security update 04-15-2010) (Windows users: Do the manual update; very easy.) See: Updating Java Do the update with Firefox closed.

Install/Update Adobe Flash Player for Firefox: your version 10.0 r12; current version 10.0 r45 See: Updating Flash -download and SAVE to your hard drive (save to Desktop for easy access) -exit Firefox (File > Exit) -double-click on the Adobe Flash installer you just downloaded to install it -when the Flash installation is complete, start Firefox, and test the Flash installation here: http://kb.adobe.com/selfservice/viewContent.do?externalId=tn_15507&sliceId=1

  • NOTE: On Vista and Windows 7 you may need to run the plugin installer as Administrator by starting the installer via the right-click context menu if you do not get an UAC prompt to ask for permission to continue (i.e nothing seems to happen). See this: http://vistasupport.mvps.org/run_as_administrator.htm
  • NOTE for IE: Firefox and most other browsers use a Plugin. IE uses an ActiveX version of Flash. To install the IE ActiveX Adobe Flash Player, same instructions as above, except use IE to download the ActiveX Flash installer.
