Browser Spying

Protect your personal information from being revealed by your browser.


  • We recommend Firefox as the basis for configuring a safe browsing experience.


  • We don’t recommend Google or Microsoft browsers since they are tied to companies that have search engines. It is therefore in their vested interest to design their browsers to cooperate as efficiently as possible with their search engines to gain and index the maximum amount of information. Firefox is far from perfect and has its own issues but they can be mitigated as described below.

  • There are other less popular browsers available. However, the uniqueness of these browsers will only aid search engines and web sites in tracking you. Anonymity is based on being one in a sea of many. Niche browsers won’t do that for you.

Tool bar and web site helper applications

Having tool bars from various companies or web site helper plug-ins installed on your browser will defeat all of the things mentioned below. Having a Toolbar from Google, Yahoo, etc. is an open invitation to track everything you do. Also, logging into a Google, Yahoo, Facebook, Microsoft or similar account will instantly allow them to track you.

How to prevent your browser from sending information to web sites

After following the steps below, you’ll be much harder to track. Coupled with our VPN service to mask your IP address and private email service, your Internet footprint will be as minimal as possible.


  • Cookies and history are the oldest of the tracking methods. Modern websites will not work well without them but they need to be managed.


  • Make sure cookies and history are deleted every time you close your browser.

1) Under Tools/Options/Privacy:

Do not check the ‘private browsing mode’ box (this is false security).

The following boxes need to be checked in order to properly clear your cookies/history:


  • Accept cookies from sites

  • Accept third party cookies (drop down box should say ‘Until I close Firefox’) Or you can set this to ask me each time.


  • Clear history when Firefox closes

Click on the Settings tab in the Privacy window.


  • Check all of the boxes so that it clears everything when you close the browser.


  • Set 'When using location bar' to Nothing

Newer versions of Firefox include a box to ‘Delete Flash Cookies’. This is important and if you have an older version, upgrade to a newer one that includes this essential option. Or, you could use the plug-in named Better Privacy to clear the flash cookies. However, it is no longer necessary with the newer version of Firefox and adds an identifying marker to your browser that is unnecessary.

Following the steps above will allow browsing on sites to proceed without issues but will clear everything every time you close the browser, which you should always do when going from one web site to another.

​2) Under Tools/Options/Security


  • Enable 'Warn me when sites try to install add-ons'


  • Disable 'Block reported attack sites' and 'Block reported web forgeries'

Note: This prevents your browsing habits from being sent to outside servers in order to determine if the site you are trying to access is dangerous. However, it also requires vigilance on your part to not be taken in by scam sites.


  • Under Passwords, disable 'Remember passwords for sites' and 'Use a master password'

3) Under Advanced Settings - General

Under Offline Storage:


  • Disable 'Submit crash reports and performance data'

4) Under Advanced settings – Network

Under General System Defaults:


  • Check 'Override automatic cache management and limit cache to 0MB space'.


  • Uncheck 'Tell me when a website asks to store data for offline storage use'.

5) Now add the plug-in No Script

This will prevent server-side scripts from running in your browser without your permission. This plug-in blocks all java scripts from running on web pages. This is both a privacy and security plug-in. By preventing the applications from running the instant you visit a page, there is little risk of malware affecting you in the background if you go to a compromised site.

Modern web sites have hidden links to a multitude of other web sites. Many of these scripts that load have nothing to do with the function of the site you are visiting. They are scripts that connect you to other sites like FaceBook, Google, Double Click, Twitter, etc. This allows these outside sites to track your activity across the Internet even though you never went to their site. By only allowing the essential java scripts that make the desired web site function, while preventing the others, you increase your privacy significantly.

After installing this plug-in most sites will not operate properly. You have to train the browser for each site you visit as to what to allow and not allow. No Script will give you a nice drop down menu telling you what sites are attempting to run scripts and then you can pick the ones that apply to the site you are on while rejecting the trackers.

By default No Script allows well known sites to operate freely. We suggest you change the default setting to restrict everything and then set all permissions manually. For example, If you go to a website that uses Google Analytics to track their visitors then Google will try to load google-analytics.com and run the java script to track you. If you have this disabled in No Script then you are less trackable without any functionality loss. All the search engines, tracking sites and social networking sites operate the same way. All of them are out to get every last bit of information on you in order to make money.

6) Firefox default registry settings

In the browser address bar type about:config and press enter.

Accept the warning about harming your system and be careful what changes you make.

  • Firefox has a feature called Prefetching that downloads pages (in the background) that it thinks you are going to click on in the future. This is a serious security flaw since in order to make this guess it’s saving lots of information of your previously visited sites.

Type: network.prefetch-next into the search bar. Right click on the option and select Toggle to change the setting to False.

  • Referer logging is used to allow websites and web servers to identify what sites you previously visited.

Type: Network.http.sendRefererHeader into the search bar and set the entry to 0.

  • With Geo-location Firefox will try and tell websites where you’re located


Type: geo.enabled into the search bar. Right click on the option and select Toggle to change the setting to False.

  • Mozilla has a feature called ‘DOM storage’ in recent versions of Firefox which can be used to track you.

Type: dom.storage.enabled into the search bar. Right click on the option and select Toggle to change the setting to False.

  • Browser Session History – number of entries increases tracking ability.

Type: browser.sessionhistory.max_entries into the search bar and set the entry to 2 or 3.


Note that this will limit how many pages the back button in FireFox will allow you to go.

  • Browser Display Fonts – Reduces the uniqueness of your browser making it more difficult to identify you.

Type: browser.display.use_document_fonts into the search bar and set the entry to 0.


Note that this will limit your browser fonts and change the look of some pages.

  • media.peerconnection.enabled – Prevents WebTRC connections from revealing your true IP.

Type: media.peerconnection.enabled into the search bar. Right click on the option and select Toggle to change the setting to False.



The above settings should be considered the minimum required to a secure and private browser. We recommend the following plugins as additional defense methods. All of these can be installed via the FireFox plug-ins menu.


  • Ghostery

  • Adblock Plus

  • HTTPS Everywhere

  • User Agent Switcher
