Re the the code
I'm using an add-on for Firefox called Ghostery - It actively blocks "viglink".
Its not perfect (it seems to slow down FF Ver 26 on Vista (business SP2) - V 26 Ubuntu 12.04 is fine ) but its certainly worth a try. {edited from earlier post]
Its blocking "viglink" as I type this: (Ubuntu-64 12.04 in use /Windows Vista 32 Bit (Business) - used too- P/C struggles)
I hope this helps.

[NB Linux Bods - I don't have any experience of 13.04 yet but this will change]
