Is there any way that I can get chrome to identify itself as a different (or unspecified) browswer?
Create a shortcut to Chrome and edit the path:
...somerandompath/chrome.exe --user-agent="User Agent String"
Some suggestions show how to modify the Chrome dll to further hard set the User Agent String. But this method allows you to keep a single unmodified install supporting multiple possible user agent strings.
This Chrome extension allows you to change navigator.userAgent and navigator.vendor in-browser: https://chrome.google.com/webstore/detail/aafciojnlamllgpkpdkbamkfgbofhgcj
It won't let you change the user agent headers, however.
