Found a great post today on Reddit by Alphabetcereal: How to max out Firefox's privacy features. (Yes, there are actually more settings under the hood than what you find in Firefox's settings!)
First of all, to give you some perspective, check out one of these sites to see how much data websites are able to get from you! [[ https://www.deviceinfo.me/ -&- https://browserleaks.com/ ]] Kinda creepy, right?
Using Mozilla Firefox out of the box will still give you a better experience and better privacy than any other browser (other than Tor, which is also developed by Mozilla, FYI)... But disabling some default features will further help increase your anonymity on the web.
On top of using most settings recommended by the guide, I also currently use the following extensions:
- uBlock Origin: (Best free adblock currently on the market)
- NoScripts: (Gives you control over javascript requests)
- HTTPS Everywhere: (Makes sure you always land on HTTPS sites when available - some sites can default to unencrypted HTTP).
- Decentraleyes (Prevents tracking from content delivery services like Google Hosted Libraries)
- 'Facebook Container', 'Google Container' and 'Amazon Container': Automatically places websites from those 3 inside "containers", basically acting like they're running as single tabs in their own browser (while they're actually tabbed in my current window) Prevents cross-tracking.
This one's a little more advanced, but can also be useful:
- Shodan: (Lets you see a website's list of open ports, public keys, and lists any known vulnerabilities they may be affected by - good to know the risks before sending any personal data over the waves!)
Pair this with a good VPN (I recommend Mullvad) and DuckDuckGo as your search engine... You're pretty much good to go. Just like a good wine and vegan cheese.
