Sometimes that warning is a false positive.

Are you using any blocking add-ons or programs? Disable them on that website.

Make sure you do not run Firefox in permanent Private Browsing mode (Always use Private Browsing mode; Never Remember History).

  • Options/Preferences -> Privacy & Security -> Firefox will: "Use custom settings for history"
  • remove checkmark: [ ] "Always use Private Browsing mode"

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 about:privatebrowsing page that get when you open a New Private Window.

  • Options/Preferences -> Privacy & Security: "Use Tracking Protection in Private Windows"

If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block (wanted) content (e.g. Adblock Plus, NoScript, Ghostery, uBlock Origin, Privacy Badger) always make sure such extensions do not block (wanted) content.
