Hello Lexx76,

Wouldn't you rather set the homepage to open a blank page ?

No, I just want uncheck all checkboxes in settings. But not myself. Because I have several profiles for testing and want uncheck all boxes for whole browser

You can check these prefs on the about:config page to see which are user set (bold).

browser.newtabpage.activity-stream.

Quote: usage statistics collection

Do you mean datareporting prefs? You can look at prefs like these:

datareporting.healthreport.service.enabled
datareporting.healthreport.uploadEnabled
datareporting.policy.dataSubmissionEnabled

Yes, data collection, but also this ticks https://i.imgur.com/scM5byU.png

You can use the Inspector (Ctrl+Shift+C) to find what preferences is controlled by a checkbox.

Thanks! But how do I can use these prefs in pref.js file? For completely disable this?

You can use an autoconfig.cfg file in the Firefox program folder to disable this feature completely and have these checkboxes grayed. In autoconfig.cfg you can use the lockPref() function to lock a pref to a specific value. In user.js you can only set a startup value via user_pref() (replace lockPref by user_pref in the below posted code). The user can still modify prefs initialized via user.js via the about:config page or via Options/Preferences.

These functions can be used in autoconfig.cfg:

defaultPref();	// set new default value, requires special data: format for localized prefs
pref();	// set pref, allow changes in current session
lockPref();	// lock pref, disallow changes

Thanks for help I place autoconfig.cfg in main folder (where is firefox.exe) but ticks stay the same about:preferences#home

I start Firefox with -p parameter and selet profile from the list. Maybe this cause the problem?

Did you place autoconfig.js in the defaults\pref folder as well? without this file Firefox doesn't know what file to load.

• https://support.mozilla.org/en-US/kb/customizing-firefox-using-autoconfig

This requires a autoconfig.js file in the "defaults\pref" folder where the channel-prefs.js file is located that specifies to use autoconfig.cfg.

//
pref("general.config.filename", "autoconfig.cfg");
pref("general.config.obscure_value", 0);

• autoconfig.cfg and autoconfig.js need to start with a comment line (//)
• autoconfig.js needs to use Unix line endings (LF instead of CR/LF).

From:

• https://support.mozilla.org/en-US/kb/customizing-firefox-using-autoconfig

<<< NOTE: The autoconfig.js file must use Unix end-of-line (LF), even on Windows systems with Firefox 60 or higher. >>>

You can verify this in a Hex file viewing utility.

Thanks! It works fine.

The data URI I posted above creates this autoconfig.js file with %0A line endings.

Can you help me with this:

Because, then I create a new profile, Im always see notification about these settings

Can I disable this notification?

Did you check the settings in Options/Preferences ?

Sorry for unlean message, I added this pref lockPref("datareporting.healthreport.uploadEnabled", false); it works fine. I start new profile several time and never see this https://imgur.com/fn7zKcB again :-)
