If I right click something on the web page http://www.tomshardware.com/ that element disappears. The same does not happen at http://www.tomshardware.co.uk/
if you want the devs to look into it then you would need to be more specific.
what browser?
what version of the browser?
what extensions are you running?
does it still happen in incognito (chrome) or the equivalent mode in other browsers?
does it happen only on the one browser?
does this issue only happen on tomshardware.com or other websites?
is it only the one set of elements as shown that disappears or is everything affected?
