That depends on the underlying OS. On Windows, from what I understood, it reads the value from a Windows library called wininet.dll, which ends up reading in the registry. See https://dxr.mozilla.org/mozilla-central/source/toolkit/system/windowsproxy/nsWindowsSystemProxySettings.cpp
Be aware that there are several registry entries that might be read, depending on the way your Internet access is configured on Windows : there is a global proxy setting, and also a proxy setting for each "Connection" configured on Windows. These values reflect the UI you have in the options of Internet Explorer. In older versions of Firefox, it was directly reading the registry, but now it's using wininet.dll to handle this. By the way, I face a bug on this system proxy detection in some specific situation : when the Connection name contains non-ASCII characters created by F5 VPN (not sure if the bug is in Firefox, in wininet.dll, or in the F5 VPN that creates the connection). See https://bugzilla.mozilla.org/show_bug.cgi?id=1218767 If someone knows who I should ping at Mozilla to get more attention on this issue, that would be helpful.
