Browser Fingerprinting

#1 Post by webfork » Tue Nov 24, 2020 11:11 am

One of my favorite things to do is to experiment with Firefox browser add-ons to adjust my online experience, but making your browser experience unique means that you become more visible online. The EFF has a site that shows how unique you are: https://coveryourtracks.eff.org/ or you can read more about the fingerprinting (both good and bad).

---

This is a topic that portable software is uniquely positioned to address due to the ability to have one or more of the same browser with various configurations on your system at any given time. So instead of (for example) Firefox Containers trying to separate Work, Banking, Personal, etc.

... you can have a separate browser for each of those operations, and have no risk of browser finterprinting suggesting who you are.

---

Some solutions from probably best to worst:
  • TorBrowser with or without the Tor network - since, if you already have a trusted VPN, you might prefer that for speed or if some sites you need ban Tor connections.
  • Firefox Extend Release version and just install the HTTPS Everywhere and NoScript (apart from some internal tweaks, this is mostly what makes up the standard TorBrowser)
  • Standard Firefox in Private Mode (enabled by checking the box in the menu pictured below) and keeping plugins to a minimum.

To be clear, the EFF recommends the use of TorBrowser or Brave, which both are built for this operation.

Finally, I've only spent a few hours researching this so additional recommendations on this welcome.

On the topic of HTTPS Everywhere: Firefox 83 just introduced optional HTTPS-only mode which is even stricter than HTTPS Everywhere. Not available in Firefox ESR yet. https://support.mozilla.org/kb/https-only-prefs

HTTPS Everywhere isn't really needed as of Firefox 83. Version 83 introduces native HTTPS-only mode - https://blog.mozilla.org/security/2020/ ... only-mode/
is it stealth? ;)

I was going to post something about the Panopticlick EFF web resource (https://panopticlick.eff.org/) , but upon refreshing I realized that it is now just a pointer to the CoverYourTracks resource webfork pointed above.
