Could the Falkon developers please enable setting the global User-Agent value, I think this is the first browser I've used that has been unable to do this in fifteen years.
Its not only a security risk but embarrassing to use a browser that you can not set its User Agent value, it only allows you to choose from a choice instead of setting your own global User Agent value and because its hardwired to identify WHICH Operating System and WHICH Version & Sub-version of OS you are using not only is Falkon screaming confidential information to every website on the Net, it is also providing more than enough to track you with it. For example the automatic warning given by Qwant when it sees it,
"Qwant helps you to better protect your privacy! Your browser sends an information called "User Agent" to websites that accurately describes the type of browser you are using. In your case the User Agent is so specific that it can be used against you to recognize and track you"
