Need a quick and easy way to tell if a website is bad news for you to visit?  With a quick installation, WOT (Web of Trust) provides security and peace of mind while browsing the Internet.


Update: Web of Trust has been found to track and sell users’ browsing history to third parties. This is a serious breach of…well, trust, so we no longer recommend using the Web of Trust extension, under any circumstances.

Setup in Firefox

The extension for Firefox installs in the same method as other extensions and once you have restarted your browser, you will see the following window asking you to accept the “WOT End-User Software License Agreement”. Click “Accept” to activate the WOT extension.

Once you have accepted the license agreement and Firefox has started, the WOT button will be located at the left side of the address bar (default location). As with other aspects of the Firefox interface, you can easily move the WOT button to a new location that best suits your needs.

The first thing that you will see in your browser window is the option to choose the level of protection that you desire. For our example, we have gone with the Basic (recommended) level. Click “Next”.

After choosing the level of protection that you desire, you will be given the option to create a WOT account. Not only will this give you access to all features, it will also give you the opportunity to rate websites that you browse or run across in your searches on the internet.

Note: You may click on the Red X to close the second window and WOT will still work without problems, but you will not have access to all available features.

For our Firefox example, here is the rating shown when visiting the How-To Geek website. All green and definitely all good!

For a more comprehensive look at how a website has been rated, click on the WOT button to show the WOT ratings window.

Setup in Internet Explorer

The setup process for Internet Explorer is similar to Firefox and uses an msi file. Before you can begin installation, you will have to accept the “End-User License Agreement”. The install process is then very quick and easy to finish up.

As with Firefox above, Internet Explorer will start and you will be asked to choose the level of protection that you desire. Click “Next”.  The location of the WOT button can be moved around the same as other toolbars on the Internet Explorer interface. For our example, it has been located on the right side below the address bar.

As above, you will have the opportunity to create a WOT account.

Note: You may click on the Red X to close the second window and WOT will still work without problems, but you will not have access to all available features.

Instead of visiting a singular website after installing WOT in Internet Explorer, we used Bing to conduct a web search for “anti spyware” in our example. As you can see, WOT is displaying a rating for each link shown in the search window (extremely nice!). This can certainly save you from getting an ugly surprise with a less than reputable website.

Here you can see the whole range of colors displaying with the links (green for the 1st, white for the 2nd, red for the 3rd & 5th, and yellow for the 4th).

Note: WOT also works nicely with other search engines as well (i.e. Google)!

Setup in Opera and Safari

To add WOT to Opera and Safari, visit the link provided below and drag the bookmarklet into your browser’s Bookmarks Toolbar. In our example, the bookmarklet was added to Opera’s regular Bookmarks Menu and to the Bookmarks Toolbar in Safari.

To use the WOT bookmarklet, you will need to click on the WOT Bookmark to activate the WOT ratings window and then click on the WOT Bookmark again to deactivate it. Simple as that!

Note: The WOT bookmarklet worked very well whether it was located in the Bookmarks Toolbar or in the regular bookmarks in our example.

Here is a quick look at the bookmarklet version of WOT in Opera…

And in Safari…

An Experiment in Google Chrome

Out of curiosity, we decided to see if we could get the WOT bookmarklet to work in Google Chrome. The result? Success!

To get the bookmarklet to work in Chrome, right click on the Bookmarks Toolbar and select “Add page…”. You will see the following window open up. Name the new bookmark “WOT”, copy the link address for the Opera/Safari bookmarklet, and paste it into the URL area. Click “OK”.

Here is our new WOT bookmarklet working very nicely in Chrome! The bookmarklet works on the same “click to activate and click to deactivate” principle as in Opera and Safari.

Note: This works equally well in the newest release of Iron Browser (version!

Different Levels of Warnings

As you visit different websites, you will run across different color ratings for those sites. What can you expect to see when the website in question causes the WOT button to display a different color than green? Here is a quick color reference guide…

If you see a Yellow color for a website, the page will display normally as shown below. You can continue to browse the website in question or close that particular tab or window. It will be a matter of your personal comfort levels with the website in question.

A quick look at the WOT ratings window for the website shown above.

If you happen to visit a website that displays a Red color, the entire browser window will look like the one below. This is a lot like the User Account Control window shading in Windows Vista and Windows 7.

Here you can see a display of the individual category ratings and the options to “Rate the site as safe” or “Ignore the warning and continue”. The best thing to do is close that particular tab or window and stay away from the website.

A quick look at the WOT ratings window for the problem website shown above. Ouch! Not good at all!

Here you can see a website that displays the White/Unknown color rating. Expanding the WOT ratings window shows that some categories have already been rated, but not enough ratings data has been collected on the website yet to give it a full color rating on the WOT button itself.


WOT is an extremely easy to use and valuable addition to any browser that only takes a few minutes to set up. Your peace of mind is definitely worth it. Relax and enjoy safer browsing!
