Disabling locked toolkit.telemetry.enabled

[KOLANICH]

toolkit.telemetry.enabled is a pref controlling telemetry verbosity, it is locked, and the lock is hardcoded into C++ code to prevent it from being disabled easily https://dxr.mozilla.org/mozilla-central/source/modules/libpref/Preferences.cpp#3213

When they have been asked about that but they have rejected the proposal to unlock it.

Fortunately, in arkenfox/user.js#271 (comment) the user @earthlng have advised to use autoconfig to disable this pref.

Autoconfig is described in https://support.mozilla.org/en-US/kb/customizing-firefox-using-autoconfig and some better docs is in https://github.com/Theemim/GeckoAutoconfigIntro .

So here is the manual:

1. create a file <firefox install dir>/defaults/pref/autoconfig.js with the text

pref("general.config.obscure_value", 0);
pref("general.config.filename", "firefox.cfg.js");

Any other prefs won't work in this file.

2. create the file <firefox install dir>/firefox.cfg.js with the text

//
lockPref("toolkit.telemetry.enabled", false);

and any other JavaScript code you want to execute.

In Firefox 62.0b1 this lock changes the locked value.

3. PROTECT THE FILES FROM NON-ADMIN ACCESS!

Thank you, @KOLANICH
I hope we support updating the repository at least in the form of creating new issues.

I wonder if this repo makes any sense. Should we migrate to ghacksuserjs/ghacks-user.js add our content to their and just translate the result?

@KOLANICH maybe pyllyukko?

@Atavic , moved the cursor to star button only to see that this repo is already starred ;) But ghacksuserjs/ghacks-user.js looks more active. I mean I have subscribed to it and I see the messages from it every day.

BTW This repo makes sense for russian users. Most of the other ones are in english.

Hello. My privacy invading friend Google brought me here. Can still confirm that this works on version 70.

For men of the penguin, at least in Arch based linux distributions, the install folder is in /usr/lib/
You're welcome, fam.
