= Firefox = '''Firefox''' is a web browser. <> ---- == Installation == Most [[Linux]] and [[BSD]] distributions offer a `firefox` package. Some also offer a `firefox-nightly` package with the experimental development branch. The self-updater will be disabled. On [[Windows]], download directly from [[https://www.mozilla.org/en-US/firefox/|Mozilla's website]]. Firefox will self-update on launch. ---- == Configuration == Behind-the-scenes configurations are made at `about:config`. === Interface Themes === The browser interface is customized through '''themes''' which can be installed either from Mozilla's registry or from a file. === Dark Mode === A web browser's support for dark mode is broken into two components: the browser interface and the web content. Firefox tries to match a system preference for light and dark mode and enforce that over both components. In lieu of a recognizable configuration, Firefox defaults to light mode. If the user explicitly sets a dark-colored theme (such as the built-in 'Dark' theme), Firefox reads this as an explicit dark mode configuration. If the browser interface is configured for dark mode (either implicitly or explicitly), it enforces that over web content as well (using `prefer-color-scheme` in the user agent). (See [[https://bugzilla.mozilla.org/show_bug.cgi?id=1529323|here]] for design rationale.) In order to force Firefox to use light mode for web content irrespective of browser interface theming, set `privacy.resistFingerprinting]] to `true` in `about:config`. (See [[https://bugzilla.mozilla.org/show_bug.cgi?id=1535189|here]] for design rationale.) ---- CategoryRicottone
