Firefox 42+ has a Tracking Protection feature that is enabled by default in Private Browsing mode. Firefox shows a shield icon at the left end of the location/address bar in case content is blocked by Tracking Protection, click the shield icon for more information. You can disable this feature in "Options/Preferences -> Privacy & Security" or via the <b>about:privatebrowsing</b> page that get when you open a New Private Window. *Options/Preferences -> Privacy & Security: "Use Tracking Protection in Private Windows" *https://support.mozilla.org/en-US/kb/tracking-protection-firefox *https://support.mozilla.org/en-US/kb/control-center-site-privacy-and-security-firefox
