Description

2 years ago
User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:46.0) Gecko/20100101 Firefox/46.0
Build ID: 20160502172042

Steps to reproduce:

On FF 46.0.1, Windows 8.1 x64, I checked the "Remote DNS" checkbox and set SOCKS5 and the DNS requests. Inspecting the traffic using Wireshark, I can see that the http packets are going through the proxy, but the DNS requests are NOT made through the proxy. FF ignores the "Remote DNS" option.

This bug is a privacy issue since the DNS request reveals the intended website, which provides plenty of info about the user's activity.

lists at least 3 bugs that this is plausibly a dupe of - going for the oldest one as that is SOP, but feel free to correct me if you think one of the others is a more precise description of what you're seeing.

As the other bugs are public, removing sec-sensitive flag here, too.
