Snap.com — this is a service that allows you to see the site to which the link leads in the form of a sketch when you hover the mouse cursor over the link. The disadvantage is that pop-ups Snap.com really annoying, they take up part of the screen space. But the main problem is — Snap.com imposed on users. If, for example, I needed such a preview, I would install an extension for Firefox.
It turns out not a very pleasant situation. Snap.com it is installed by the site owners, despite the fact that not all visitors like it. There were two exits at once.
First, block Snap.com you can if you go to the service's frequently asked questions page. There you can find a link to a java script that turns off Snap.com.The disadvantage of this method is the use of cookies. As soon as you clear your browser of them, you will observe the windows again Snap.com .
The second method is more effective, but it will suit Mozilla Firefox users. Install the AdBlock Plus extension that blocks ads. Restart Firefox to make the addon work. Then right-click on the AdBlock icon and go to the Settings, and there add a new rule:
spa.snap.com/*
