I need to review a couple of videos embedded in websites for some consultancy work I am doing.

When I click on the links I get a blank link on the webpage with a very small icon in the top left of the screen (coloured white red, green and blue). I assume this is some form of security setting on my PC, but don't know how to change it to allow me to access the videos.

Any help is much appreciated as need to finish the report before I go off on holiday on Sunday.

Thanks in advance
