Yes, WOT, not what. It stands for Web Of Trust. WOT is an addon for Firefox, Chrome, Opera and IE. Once installed, it can scan links in search engine results and web email. When it finds dangerous links, it lets you know with red and yellow symbols, as shown in this video below.
As you can see, it’s not safe to search for screensavers. That is, it’s not safe unless you are using WOT or a service like it. You’ll see similar results in your online email, such as Yahoo, Hotmail or Gmail. I’d say it’s a must have addon for those new to the internet.
Today, I received a notice from WOT telling about the addition of social networking sites to their link scanning. What does this mean? Take a look at Facebook with the new WOT addon for Firefox.
