It would be awesome to turn it into an extension that makes it a single toggle.

I wouldn't use it since it: - Disables the malware and phishing lists/warnings. - Disables HTML5-video DRM (even if this has nothing to do with leaking data). - Geo location already brings up a popup (and thus disabling it seems petty).

Aside from the things you listed, it's ok to disable the other things?

Don't forget about this; "media.peerconnection.enabled = false" WebRTC leaks IP when you use TOR/VPN, test it with ipleak.net "beacon.enabled = false" Blocks https://w3c.github.io/beacon/ analytics. Also recommend using plugins; uBlock, NoScript if you use VPN.

How can WebGL leak your IP? Did you confuse it with WebRTC?

Yes sorry ^_^ I meant WebRTC :) Edited!

So how about a checkbox for each setting?

Seems like a bad idea turning off phishing notifications and browser warnings http://kb.mozillazine.org/Browser.safebrowsing.enabled Firefox 2.0 incorporates the Google Safe Browsing extension in its own Phishing Protection feature to detect and warn users of phishy web sites.

It does send your IP address to Google, when you download the filter. And I can't tell if "Enhanced Protection" is enabled which actually sends your URLs to Google.

How exactly does reader.parse-on-load.enabled leak privacy? Isn't everything parsed locally?

I too am curious about this one.

I would rather live in a browser without video support, than with DRM

I think using a blocker extension like uBlock Origin restores (at least partially) this functionality without involving Google.

Right, but then you're just changing who you leak data to, you're not stopping the leak.

EDIT: wow, downvotes? Getting a list from EasyList is just as much a leak as getting a list from Google. Someone has your IP either way.

Another thing worth noting is that if you are using Debian-rebranded Firefox (Iceweasel), you have a very unique user agent that is easy to track.

There is a bug opened (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=748897), but as far as I know, no simple solution exists yet. You can change the user agent with an extension to keep it identical with the most popular Firefox version, but then you have to manually keep it up-to-date.
