There are numerous websites explaining how to tweak Firefox preferences with about:config
Here is just 1 example

For those who test distros, it is a hassle to tweak Firefox again and again in the new installed distro.

Here is a way to save this time by creating a file and copying it into every new Firefox installation once, restarting Firefox and there you go with all the tweaks.

Short instruction:

1.Create a text-file with leafpad or pluma or whatever file-manager you like.
Name it user.js

2. Insert the about:config settings into this  user.js  file.

3. Place the user.js  file into the profiles folder of Firefox.

4. Start / restart  Firefox.   Done

Here is the complete description for this excellent method:

Here is a part of my user.js file to give you an idea how easy this method is:
Code: [Select]
// Geolocation API abschalten
user_pref("geo.enabled", false);
user_pref("geo.wifi.uri", "");
user_pref("", 1);

// WebRTC deaktivieren
user_pref("media.peerconnection.enabled", false);
user_pref("loop.enabled", false);

// WebGL deaktivieren
user_pref("webgl.disable-extensions", true);
user_pref("webgl.min_capability_mode", true);
user_pref("webgl.disable-fail-if-major-performance-caveat", true);
user_pref("webgl.disabled", true);

// Clipboard Events deaktivieren
user_pref("dom.event.clipboardevents.enabled", false);

Thanks, berliner. Another method that I recommend is the FEBE add-on. It allows you to schedule complete backups of everything in Firefox from your extensions to your profile (about:config changes). If you need to carry them over to another distro, simply install FEBE and restore the last FEBE snapshot that it created.
