Firefox 18 Beta. Javascript is activated. Flash Player, sends error that javascript in NOT activated and won't play, or install uptdate.


I'm running Windows 8 Pro. Flash Player worked in the past, with Windows 7, intermittently, mostly working.

Now, javascript is checked, as has been, only in the last couple months, even before Windows 8, Flash Player sends the error message that javascript is NOT enabled. All my windows settings the same as before when it worked.

I'm running the latest release of Norton 360, for a firewall, virus protection etc. Which I was running before this error began. Please help

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 Reset Firefox – easily fix most problems article.
