Do you possibly have enabled "Resist Fingerprinting"?

You can check this pref on the about:config page to see if resist fingerprinting (RFP) is enabled and if this pref is user set (bold) reset to false via the right-click context menu.

  • privacy.resistFingerprinting = false

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.


Check that you do not run Firefox in compatibility mode. You can open the Properties of the Firefox desktop shortcut via the right-click context menu and check the "Compatibility" tab. Make sure that all items are deselected in the "Compatibility" tab of the Properties window.

The issue concerning compatibility solved the problem. It was set for Windows XP. Thanks for your time and answers.
