How to check if your browser is leaking your identity?

[Ceginn]

Yo, been reading up on how sites track you even without cookies, and now I am properly paranoid about my setup. I have got a few privacy extensions installed, but I honestly have no clue if they are actually doing anything or if I am still leaving a massive digital trail everywhere I go. Is there a way to see what my browser is really telling sites behind the scenes?

The unsettling truth is that even incognito and a VPN do not hide all the subtle details your browser leaks, things like your timezone and installed fonts combine into a profile that is often unique enough to pick you out of a crowd. There are a handful of tools out there that scan these parameters, and one worth trying is a browser fingerprint checker, it runs through all those signals and shows you how identifiable your current setup really is. A solid one is available on this site https://gologin.com/check-browser/ .

Run the fingerprint check before and after you toggle your privacy extensions, so you can see which ones are actually reducing your uniqueness score and which ones are just sitting there looking busy. A lot of popular add-ons do nothing for fingerprinting and some even make you more identifiable by adding a weird combination to your profile.

MoreLogin aside, the easiest way is to run your browser through a few fingerprint and leak tests. Check IP/DNS/WebRTC first, then look at canvas, WebGL, fonts, timezone, language, and screen size on tools like BrowserLeaks or IPLeak. Privacy extensions can help, but too many extensions can also make your browser more unique.
