We’ve found a simple work around to continue using Firefox with the Biometric Scanner.

  1. Deactivate Auto update in Firefox
  2. Download firefox 51.00 – Link to firefox 51: https://ftp.mozilla.org/pub/firefox/releases/51.0/win32/en-US/Firefox Setup 51.0.exe
  3. Close Firefox  and Execute  Firefox Setup 51.0
  4. Open Firefox and make sure Auto updates are still off
  5. Run firefox and open TWS
  6. Make sure to click “Allow” from the pop up window. Click “Remember” from the second pop up to do thin only once.
