TEST YOUR BROWSER SECURITY
Qualys BrowserCheck
BrowserCheck scans your browser's security settings by installing a plug-in to check for data encryption, browser extensions, and add-ons. The service gives you a clear analysis of all your security settings, as well as version history and any available updates. You also get the option to fix insecure extensions or outdated versions directly through the results page.
Panopticlick
This service takes a different view at browser security. There are many ways in which sites can track you and one of those ways is the uniqueness of your browser fingerprint. Panopticlick determines how many bits of "identifying information" your browser sends out and how they contribute to your unique fingerprint. The higher your bit count, the easier it is to track you. Characteristics that contribute to your browser fingerprints include plug-in details, time-zone, resolution, fonts and cookies.
PC Flank
The PC Flank site provides services to test the overall security of your computer, including stealth tests, viral infection tests and browser tests. The browser test determines if your system is giving away personal information, your location, or your ISP, and also gives you specific recommendations based on the test results.
Browserscope
Browserscope gives you a comprehensive comparison of every aspect of all the top browsers. Apart from comparing the test results for different browsers, you can also use the site to test your browser with its specific settings for different features, including security. The personal browser security check gives you an analysis of test results for various APIs, cross-site scripting, privacy settings and security settings, giving your browser a final score out of 17. You can even compare your result with results for other browsers.
BrowserSPY.dk
