Screwfix.com (broken website)

Edit Subject

Hi,

Link below to the problem site. When looking at an individual product to purchase on this site, there is an image on the left with an embedded 'Enlarge Image' link. This will not work unless coremetrics is white-listed for the site. However, when the image pop-up is closed the Ghostery tool-bar button will not work (no response) even if I refresh the page. Seems I need to open another tab and return to screwfix.com before the Ghostery button will respond, but even then it won't show all remaining blocked trackers unless I refresh the page. Now I know what's going on I can deal with it but the behaviour seems odd.

This is Firefox 27.0.1, Ghostery 5.1.1, No other conflicting / similar FF add-ons.

Thanks.

EDIT: Updating this to say that the Ghostery button frequently becomes unresponsive on other sites as well - although the blocking still seems to be working.
