Why do you want to suppress the agent info?

The agent string is used at web servers to make websites fit and optimized to your browser.

If you want to suppress it anyway, you can use browser add-ons like User Agent Overrider or User Agent Switcher.

Is it possible to do it with pfsense ?
so all it will be block for all the computers in the net ?

viragomann

No, not by pfSense itself. This is part of HTTP. Maybe it can be changed or suppressed on a proxy like squid. I don't know.
There is a special topic for that in the forum: https://forum.pfsense.org/index.php?board=60.0

blocking that is going to break many a website, or at min make sites not look right.

Are you sure ?

When I had Squid 2 installed
i marked these two

Disable X-Forward
Disable VIA

and the site did not see these details (ip,resolution,system,etc etc)
And browsing was fine

He's right. You didn't disable the user agent by doing that, that just disables the headers that Squid adds, so remote sites won't see you're going through a proxy.

firefox

so how this details Were blocked ?

They are part of the HTTP GET browser call (Yep, it's your browser who tells the web server who / what / where / …. so using a less noisy browser will help here)
Squid probably dives into the IP packets and removes them on the fly ...
