compact mode

mozilla removed the compact density after the redesign, to add it back go to `about:config` and toggle the `` option. now you can select it in the customize page again

disable mozilla telemetry

in general settings, scroll down to "browsing" and uncheck the "recommend extensions/features as you browse" options

in settings > home, set new windows and tabs to "blank page", and just in case disable all the checkboxes under "firefox home content" too

in settings > privacy & security, scroll to "firefox data collection and use" and disable all of the checkboxes

privacy hardening

block ads!
ublock origin

block cookie pop-ups!
i still don't care aobut cookies

remove tracking content from urls (eg. ?utm_source=, &utm_medium=, &utm_content=, etc.)

now if you want to go the extra mile, there's chameleon. it lets you spoof your user-agent, as well as many other fingerprinting-resistance features like spoofing the output of certain javascript commands. chameleon will break websites but you can add exceptions

enhanced tracking protection

firefox comes with an amazing tool called enhanced tracking protection. go to settings > privacy & security, choose the "custom" option, set cookies to "all cross-site cookies", and tracking content to "in all windows". if you use the dark mode, keep the suspected fingerprinters on only in private windows, and use the following for fingerprint resistance instead:

resist fingerprinting w/ dark theme

to enable fingerprinting resistance go to `about:config` and toggle the `privacy.resistFingerprinting.pbmode` flag to true, and set `privacy.fingerprintingProtection.overrides` to "-CSSPrefersColorScheme" too

clear cookies on exit

one of the best things you can do for your privacy is clear the cookies of all unknown websites when you close the browser. go to settings > privacy & security > cookies and site data, enable "delete cookies and site data when firefox is closed", and go into "manage exceptions" to whitelist sites you regularly use

there's also an extension which lets you do this on the closure of tabs as well
cookie autodelete


firefox has a unique feature called containers, which are a way to sandbox cross-site cookies, session data, etc. between websites

sandbox large companies & monopolies
facebook container
google container
amazon container

manually assign websites to containers
you can assign your search engine to an "untrusted" container, so general web browsing is sandboxed
you can sandbox your banking websites, retail outlets, or anything that handles sensitive information like payment details
sandbox microsoft as well!
