Additional notes

  • I am using the extracted tarball to use Pale Moon, no installation.
  • I am a new user, so forgive me if this is because of some silly mistake!

On my end, Pale Moon does not properly apply my user.js file. Here are the contents:

// user.js user_pref("canvas.poisondata", true); user_pref("device.sensors.enabled", false); user_pref("dom.idle-observers-api.enabled", false); user_pref("dom.keyboardevent.code.enabled", false); user_pref("geo.enabled", false);

user_pref("layers.acceleration.enabled"; true); user_pref("network.http.pipelining.aggressive", true); user_pref("network.http.pipelining.max-optimistic-requests", 5); user_pref("network.http.pipelining.maxreqests", 20); user_pref("network.http.pipelining.maxsize", 240000); user_pref("network.http.referer.spoofSource", true); user_pref("network.http.referer.trimmingPolicy"; 2); user_pref("network.http.referer.XOriginPolicy", 2); user_pref("network.http.referer.XOriginTrimmingPolicy", 2); user_pref("webgl.disabled", true);

What's strange is that this doesn't seem to be a matter of incorrect syntax, or file misplacement, or anything that could fundamentally just outright prevent the user.js from being read. In the first block, the prefs shown are applied; in the second block, they are not.
