While maintaining privacy when accessing web sites probably has never been more important than it is today, faking Referer and User-Agent headers is both obsolete and counterproductive:
(a) Most web sites require HTTPS, thwarting manipulation attempts to HTTP headers in transit. Given todays' internet landscape, faking these headers is unlikely to work for the vast majority of web sites.
(b) It is trivial to detect faked HTTP User-Agent headers by obtaining corresponding browser information via JavaScript. Any difference most likely indicates (trivial) header manipulation attempts, hence rendering this feature useless if browsers do not behave in the same manner, which we cannot control on IPFire.
(c) Especially static Referer headers make users stick out like a sore thumb, as nobody else in the world is likely to have the same Referer set _all the time_.
Modern browsers attempt to strip sensitive information from Referer headers, or ditch them completely, particularly to 3rd party sites.
Given the state of the web ecosystem as we know it today, enforcing privacy in a centralised manner does not even come close to being sufficient. Without gaining control over users' browsers, their settings, and their infrastructure (such as setting up terminal environments for accessing the web, preventing hardware fingerprinting), a centralised attempt will at best fail, if not making things worse, as highlighted in (c).
Therefore, removing these features from the Squid GUI is the least worse option we have. We should not give our users a false sense of privacy.

Hello,
I wasn’t really in favour of this when I read the subject, but I find your argumentation quite convincing.
However, this means that we will have to rethink the whole proxy thing at some point, because there are another hundred buttons that do not work any more which I would throw into the same bucket than this.
My argument against merging this would be that we are removing yet another “feature”.

While maintaining privacy when accessing web sites probably has never been more important than it is today, faking Referer and User-Agent headers is both obsolete and counterproductive:
(a) Most web sites require HTTPS, thwarting manipulation attempts to HTTP headers in transit. Given todays' internet landscape, faking these headers is unlikely to work for the vast majority of web sites.
Agreed.
(b) It is trivial to detect faked HTTP User-Agent headers by obtaining corresponding browser information via JavaScript. Any difference most likely indicates (trivial) header manipulation attempts, hence rendering this feature useless if browsers do not behave in the same manner, which we cannot control on IPFire.
(c) Especially static Referer headers make users stick out like a sore thumb, as nobody else in the world is likely to have the same Referer set _all the time_.
That used to be the case though.
Modern browsers attempt to strip sensitive information from Referer headers, or ditch them completely, particularly to 3rd party sites.
Given the state of the web ecosystem as we know it today, enforcing privacy in a centralised manner does not even come close to being sufficient. Without gaining control over users' browsers, their settings, and their infrastructure (such as setting up terminal environments for accessing the web, preventing hardware fingerprinting), a centralised attempt will at best fail, if not making things worse, as highlighted in (c).
Therefore, removing these features from the Squid GUI is the least worse option we have. We should not give our users a false sense of privacy.
True, but what about all the other things?
