Like Angie's List and other reputation services, WOT is powered by individuals with real-world experiences to share. WOT for Firefox places WOT's trust meter between Firefox's address bar and search bar for instantaneous feedback about the Web sites you visit. It turns from green to yellow to red as the danger increases and displays site ratings when you click it. You can also share your experiences and views through your free WOT account and social media options.
WOT for Firefox runs not only in Firefox but also Firefox-based browsers; even 64-bit Cyberfox. During the setup process, we could sign in or create an account, which enables feedback and social features. But you don't have to sign up for WOT; it works just fine without an account, as we verified. Signing up for a free WOT account is easy, though, (you can do it through Facebook) and minimally intrusive. Clicking MyWOT opened our account page. We could access WOT's settings from the icon's menu or from Firefox's add-ons page. Setup finished with a Guided Tour of WOT's features, but more support options are available.
WOT's icon is perfectly placed to be visible but unobtrusive -- easy to spot when the color changes, but otherwise part of the background. Hovering the cursor displays the site's rating; clicking the icon displays the site's Trustworthiness, Vendor Reliability, Privacy, and Child Safety ratings. We could choose between warning pop-ups or warning pop-ups and site-blocking, configure reputation icons, and enable Parental Control, among other options. We browsed to a questionable site. WOT's icon turned red to flag the site's poor reputation (That's why we picked it!). WOT for Firefox kept us informed, which helped keep us safe.
