 275         Privacy Browser's default user agent is <code>PrivacyBrowser/1.0</code>.

 278
 279       <para>
 280         Over the years user agents have become quite lengthy,

 282         In the modern world they serve almost no good purpose, but some web developers still think they need them so they can send different version of their website to different browsers.
 283         Some servers <ulink url="https://www.stoutner.com/user-agent-problems/">refuse to function correctly</ulink> if they don't like the user agent that is sent.

 285
 286       <para>
 287         At some point in the future Privacy Browser will send no user agent by default.
 288         Not only is that currently impossible because the Qt WebEngine doesn't allow you to not send a user agent (I will probably have to fork it to enable that functionality),
 289         but even web servers that don't care what the user agent is often refuse to send an answer if there is no user agent at all.
 290         Getting rid of this relic of the internet is going to take some time and a retraining of common expectations.

 319         Hopefully, as more people become aware of what HTTP pings are, web sites will become more embarrassed about using them.
 320         This is a classic example of how those who wrote the HTTP specs do not have the best interests of internet users at heart. I would like the day to come where they are removed from the specs.
