Firefox Browser Settings, Configuration, and Add-Ons/Extensions for Privacy, Security, and OSINT Research
How I secure, privatize, and customize my Firefox browser to protect personal privacy and gather open source intelligence
The Firefox web browser can be, in my opinion, the most private, secure, and productive way to browse the internet… but only when it’s configured properly.
For those of you willing to take the time to properly configure Firefox, and learn to use browser extensions, I believe this is the best way.
For those of you not willing to take the time, I highly recommend Brave Browser over Chrome, Safari, etc. as the best “out-of-the-box” alternative.

- Change “Default Search Engine” to DuckDuckGo
