# user-agent-rewriter
|
|
|
|
## What it does
|
|
|
|
This extension uses the webRequest API to rewrite the browser's User Agent header, but only when visiting pages under "http://useragentstring.com/".
|
|
|
|
It adds a browser action. The browser action has a popup that lets the user choose one of three browsers: Firefox 41, Chrome 41, and IE 11. When the user chooses a browser, the extension then rewrites the User Agent header so the real browser identifies itself as the chosen browser on the site http://useragentstring.com/.
