Web of Trust for FireFox gives you the chance to see how reputable the sites that come up in your search engine results, social media links, Wikipedia resources, and web-based e-mail are. When such links come up during your browsing experience, traffic lights will be displayed next to them. As you would expect, a green light means that the site has a good reputation and can generally be trusted while a red light lets you know that there is likely spyware, a virus, or other potential problems on the site. Yellow suggests that the site is likely safe, but you should be careful with your information and any downloads that come from it.
Whiel the traffic lights themselves provide a quick point of reference for the sites that you visit, more information can be found, including feedback from some of its users, by clicking on the light. This helps you to make fully informed decisions about whether you want to proceed to access the site and what specific problems have arisen with it in the past. Several media outlets have covered Web of Trust for Firefox, including CNET, PC World, and the New York Times. To find out more about the extension, you can visit mywot.com.
