Hi Bob

Which website is this happening with?

Do you have any add-ons installed in Firefox?

Hi

I understand that this was not a problem with Firefox, but a change with the YouTube website that did not work as intended. I understand that the YouTube team have rolled this change back and it should be fine now.
