# @file Firefox Settings / Add-Ons / Profiles
# @brief This script configures system-wide settings, sets up Firefox Profile Switcher, creates various profiles from different sources, and installs a configurable list of Firefox Add-Ons.
# @description
#     The Firefox setup script performs a handful of tasks that automate the setup of Firefox as well as
#     useful utilities that will benefit Firefox power-users. The script also performs the same logic on
#     [LibreWolf](https://librewolf.net/) installations.
#
#     ## Features
#
#     * Installs and sets up [Firefox Profile Switcher](https://github.com/null-dev/firefox-profile-switcher)
#     * Sets up system-wide enterprise settings (with configurations found in `~/.local/share/firefox`)
#     * Sets up a handful of default profiles to use with the Firefox Profile Switcher
#     * Automatically installs the plugins defined in the firefoxAddOns key of [`home/.chezmoidata.yaml`](https://github.com/megabyte-labs/install.doctor/blob/master/home/.chezmoidata.yaml) to the Standard and Private profiles
#     * Configures the default profile to clone its settings from the profile stored in firefoxPublicProfile of `home/.chezmoidata.yaml`
#     * Optionally, if the Chezmoi encryption key is present, then the default profile will be set to the contents of an encrypted `.tar.gz` that must be stored in the cloud somewhere (with the firefoxPrivateProfile key in `home/.chezmoidata.yaml` defining the URL of the encrypted `.tar.gz`)
#
#     ## Profiles
#
#     The script sets up numerous profiles for user flexibility. They can be switched by using the Firefox Profile Switcher
#     that this script sets up. The map of the profiles is generated by using the template file stored in `~/.local/share/firefox/profiles.ini`.
#     The following details the features of each profile:
#
#     | Name             | Description                                                                                 |
#     |------------------|---------------------------------------------------------------------------------------------|
#     | Factory          | Default browser settings (system-wide configurations still apply)                           |
#     | default-release  | Same as Factory (unmodified and generated by headlessly opening Firefox / LibreWolf)        |
#     | Git (Public)     | Pre-configured profile with address stored in `firefoxPublicProfile`                        |
#     | Standard         | Cloned from the profile above with `firefoxAddOns` also installed                           |
#     | Miscellaneous    | Cloned from the Factory profile (with the user.js found in `~/.config/firefox` applied)     |
#     | Development      | Same as Miscellaneous                                                                       |
#     | Automation       | Same as Miscellaneous                                                                       |
#     | Private          | Populated from an encrypted profile stored in the cloud (also installs `firefoxAddOns`)     |
#
#     ## Notes
#
#     * The Firefox Profile Switcher is only compatible with Firefox and not LibreWolf
#     * This script is only designed to properly provision profiles on a fresh installation (so it does not mess around with pre-existing / already configured profiles)
#     * Additional profiles for LibreWolf are not added because the Firefox Profile Switcher is not compatible with LibreWolf
#
#     ## Links
#
#     * [System-wide configurations](https://github.com/megabyte-labs/install.doctor/tree/master/home/dot_local/share/firefox) as well as the location of the `profile.ini` and some other configurations
#     * [User-specific configurations](https://github.com/megabyte-labs/install.doctor/blob/master/home/dot_config/firefox/user.js) added to all profiles except Factory
