Anyone who has installed Skype may have noticed that it likes to format phone numbers it comes across on websites to allow you to call up with just one click:
All very useful but it can often mess with the design of a site, and is particularly annoying when admiring a new site design (though fortunately it doesn’t come into play on localhost).
It might seem trivial to some but it really bugs me, so if you wish to switch this off you need to disable the Skype add on that is installed on your browser.
Rather than spend 10 minutes messing around within the actual Skype application looking for an option that is not there, try the following:
Tools -> Add Ons -> Select Skype Add On from the list and disable
Tools -> Internet Options -> Programs -> Manage Add Ons -> Select Skype Add On from the list and disable
