ITV iPlayer not working on Firefox

[Smiley G]

Today I decided to watch Lucan using Firefox with the media add-on. For some reason it would not work and I got a pop-up message stating that I had Ad-Blocking software installed and that I would need to remove or disable it before continuing using iPlayer.
I disabled Ad-blocker but nothing changed.
I uninstalled Firefox, re-installed it to no avail.
BBC iPlayer & Channel 4 OD still work perfectly.
Has anyone got any suggestions?
