tempfox #

A Firefox user.js with personal preference overrides.

Installation #

Copy user.js into your Firefox profile directory:

cp user.js ~/.mozilla/firefox/<profile>/user.js

Preferences are applied on the next Firefox launch. To make a preference permanent, it must remain in user.js — Firefox will not revert it automatically, but the GUI can override it until the next restart.

What it sets #

• Dark mode
• Disables first-run and update pages
• Disables default browser check
• Disables about:config warning
• Disables telemetry and data reporting notices
• Disables the sidebar and vertical tabs
