Firefox users can choose between several website and link information add-ons including Web of Trust or AVG Linkscanner. The Firefox add-on Link Extend takes the concept to the next level. It combines computer safety, child safety, company ethics, and popularity tools in one add-on. The computer safety services alone consist of the eight services Web of Trust, Siteadvisor, Google Safe Browsing, Browser Defender, Web Security Guard, Norton, Dr. Web and Compete safety information.
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.
