Context Explorer is a sidebar designed for the Mozilla Firefox browser whose utility is to associate local resources of your system to the web pages you are viewing.
For example, imagine that you are browsing the user account of your college or university, and you need to open a specific document for a class. All you have to do is click on your Mozilla Firefox sidebar, because Context Explorer will have already found it. You will not need to waste time diving among thousands of folders and disk drives manually until you find that document.
You can free download Context Explorer 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
