FireFox Privacy Guide

Firefox has many features but we have chosen it because there are portable usb versions of firefox out there or regular versions and all of them can be tweaked and easily programmed to keep your browsing history safe

we will cover useful plugins, edits using about:config and how you can make firefox more difficult for websites to fingerprint and to trace

your browser gives a lot of information out about you and if you head over to you can see what your browser reveals websites can view and log, location, browser versions, what cpu and system you are using and much more but with my guide we will be spoofing everything and even causing firefox to forget our history if we choose too

in an ideal world we would place portable version of firefox on a fast usb 3 device with encryption and there will be little to no privacy issues especially if you follow this guide

Most of our work will be done using either about:config which you type in to Firefox Address bar and hit enter “Accept the Risk Warning” or it will use plugins.

Gps Location Privacy

First Privacy concern we will spoof our GPS location by going in to about:config and add a new string called geo.wifi.uri and entering this value and saving it

data:application/json,{“location”: {“lat”: 64.963051, “lng”: 19.020836}, “accuracy”: 7.0}

for the Lat & Lng settings go to and look up coordinates for the location you want to be seen as coming from (wise to make it match your vpn server location) we just put some random Longitude and Latitude in

Cpu Info Spoofing

This helps prevent websites reading your true cpu information

go to about:config add a new string called general.oscpu.override and enter this in the string: Apple Inc

you can add anything you want from ARM64, ARM, Intel, Amd here are some examples you can use

Operating system
oscpuInfo string format
OS/2 Warp x (either 3, 4 or 4.5)
Windows CE
WindowsCE x.y1
Windows 64-bit (64-bit build)
Windows NT x.y; Win64; x64

Output of uname -s plus “i686 on x86_64”

to test your new string to go

Plugins for Privacy

Please note that plugins come and plugins go, some become outdated and newer versions of Firefox may not support them

CyDec Platform AntiFingerprintby Heilig Defense firefox plugin

this helps prevent web browser fingerprinting “Google Web Browser Finerprinting”

NoScript (tor uses noscript to block scripts from running on your browser

Ghostery – Privacy Ad Blocker blocks Ad trackers Privacy Badger is another Alternative becuase who doesn’t love Badgers?
