Why is this marked sensitive?
Firefox is a terrible browser, and the reason it is terrible is more political than technical at this point, but the same junk that spies on you to sell ads can also sell more of your private information to government.

Installing Brave.
Brave basically invents new ways of screwing around with Web tracking technology and makes them part of the browser, even substituting tracking libraries from many Web sites with substitutes (Sugarcoat) which implement the minimal API for the site to function while removing the functionality that spies on the user.
See my guide to installing and configuring the Brave Web browser on Debian 12.
Installing LibreWolf.
LibreWolf is a fork of Firefox which removes the spyware and junk in Firefox and enhances your privacy.
If you require a Firefox-style browser, you may want to use this instead.
