Easily pose as another browser by changing the User-Agent header.*

Pretending to be a different browser can be useful in a number of different situations:

  • Some web pages require you to log in or buy a subscription to view their content, but give full read access to search engines.
  • Some web pages determine whether you're using a mobile or desktop browser based on your user-agent.
  • Some web pages require you to use a specific browser to access their site.
  • And potentially more…
Note that your browser will not magically morph into a different piece of software just because it's pretending to be some other software. If a web site locks you out because your browser does not support a feature they require then changing the User-Agent will not make any difference.
  • Also changes navigator.userAgent, as well generating convincing values for several of the other navigator.* properties.
