Type in the address bar about:config (press Enter)

And set its value to false

A role for configuring Firefox, including addons, preferences and css styles.

Notes:

A Firefox profile named 'default' will be created if it doesn't already exist.
If any addon being installed is a 'complete theme' addon, it will be set as the selected theme (this is the default behaviour of the firefox-addon role dependency).

Requirements

Currently the role has only been tested against Fedora (23) hosts, but in theory should work for all Linux variants.

An Ansible Role that installs Firefox, the firefox addons mentioned in Firefox Kompendium, the user.js from Ghacks, some offline fonts so remote fonts are not required and some search keywords for the Url-Bar. The role is compatible with RHEL/CentOS, Fedora, Debian and Ubuntu. Be aware that while this config blocks a lot of tracking, which helps bot with privacy and security it give the user a very unique fingerprint aswell. Thats why it´s still recommended to use the TOR Browser for normal surfing and this firefox config for functions that websites that require a login (e.g. forums, social media, online banking or online shopping).
