Multiple services are available in the other website information categories as well. The best part is that these information can be easily accessed. Options are to display a toolbar in Firefox that displays some of the information right away and offers one-click access to everything else. Not everyone wants to use a toolbar on the other hand. That’s why there is also the possibility to right-click on a link to display the information in a overlay window. An overall rating is displayed on top of each category that is computed from the results of all single results.

The add-on does not slow down the web browsing experience noticeably.
