There are a few websites that are designed for browser security test purposes. For instance, sites like BrowserScope, BrowserSpy, PCFlank, Qualys Browser Check and Panopticlick are all efficient testing tools. All these sites test browsers, discover any security shortfalls or privacy vulnerabilities and recommend the necessary solutions.
The testing method used by most of the websites varies across two options. The first is for the user to run a quick scan or install a plugin to know if the browser has any security issues. The other method used by some websites is to check the browser’s configuration and give a uniqueness score.
