User Agent String
Loading...
Why does this matter?
Every time you visit a website, your browser sends a "User Agent" string. This string tells the server what operating system and browser version you are using so it can serve you the correct version of the page.
Fingerprinting
Unique combinations of screen size, OS version, and browser plugins can be used to create a "fingerprint" that tracks you across the web, even without cookies.
Debugging
Web developers often ask for your "User Agent" or screen resolution when troubleshooting bugs, as websites can look different on different devices.
