Stop Firefox leaking data about you.
 

Hello,

I know here are a lot of talks about WebRTC leak and some others. But guys, you are missing a lot more.
So here are a list which aims to block core Firefox features, which actively leak data to third-party services (as opposed to attempts of sites to track you or otherwise passively collect information). As it isn't always easy to draw a strict line, the most critical passive data faucets like WebRTC are also mentioned.

To change the settings open about:config.

Google Safe Browsing

Leaks the browsing history to Google. Note that disabling Safe Browsing exposes you to a risk of not being stopped from visiting malicious or phishing sites.
browser.safebrowsing.enabled = false
browser.safebrowsing.downloads.enabled = false
browser.safebrowsing.malware.enabled = false
Firefox stats collecting


Stability and performance reports.

datareporting.healthreport.service.enabled = false
datareporting.healthreport.uploadEnabled = false


Usage statistics.

toolkit.telemetry.unified = false
toolkit.telemetry.enabled = false


Encrypted Media Extensions (DRM)

A binary plugin (closed-source) is shipped with Firefox since v38. It enables playback of encrypted media and lets you use e.g. Netflix without Microsoft Silverlight. To completely remove the plugin you would have to install an EME-free build of Firefox.

media.eme.enabled = false
media.gmp-eme-adobe.enabled = false


Firefox Hello

Firefox connects to third-party (Telefonica) servers without asking for permission.

loop.enabled = false


Pocket integration

A third-party service for managing a reading list of articles.

browser.pocket.enabled = false


Search suggestions

Everything you type in the search box is sent to the search engine. Suggestions based on local history will still work.

browser.search.suggest.enabled = false


WebRTC

Leaks the real IP when using VPN/TOR. Description and demo.

media.peerconnection.enabled = false
Instead of completely disabling WebRTC you could also make it connect over the default route only using:

media.peerconnection.ice.default_address_only = true


Geolocation

geo.enabled = false


Adobe Flash

plugin.state.flash = 0


I hope this will help to someone.. ;)

Hahah, good thread!

However I think that most of these things are largely irrelevant to stealth as Google for example, is not connected to eBay/PayPal anyhow.

It's good for anonimity but when it comes to stealth that's overcomplicating the matter further.

If you are interested in being genuinely anonymous, on the deep web there are many more things discussed than this. Hell, you can even be traced from behind a VPN / TOR, so you would need to look into setting a VPN chain, and then it goes into fundamentals of how networks work, and it's an never ending topic. Not to mention the DNS leaks, all the possible browser fingerprints, tracking pixels and even your ISP cooperating and actively logging all of your navigation history to share with authorities (VPN/TOR bypasses it... but they still log connection times, end IPs, and through DNS leaks they can bypass VPN/TOR unless you fix them). There are enthusiasts looking into this topic day and night. However, the question is, is it really worth your time?

Easy Fix, VMWare.......No leak, No Fuss, No coconuts.

Cocunuts you say...

And still your list misses A LOT more :)

Firefox is leaky as hell (not saying other browsers are better ;) ) Trying to fix it with add-ons and config alone is a futile attempt.

Never do that using addons.
Paypal sees addons and plugins installed and if there is any ****ty plugin like canvas or request or user-agent modifier etc, they will limit you in no time...maybe after a week.

VMWare + Portable Browser = Sucess
