From a site that reads browsers
Which browser tells websites the least about you?
None of them tells a website nothing. Every browser hands any page you open your network address, the size of your screen, the time zone your clock is set to and everything you do on the page, with no prompt. Where they differ is the machine underneath. Chrome and Edge give the most: the exact graphics chip, every font you installed, the battery. Safari and Firefox hide some of it and blur more in their private windows. Brave changes or hides the most by default. The table below sets it out, reading by reading.
We can compare them because the demonstration on this site, Snitch, takes these readings from every visitor who lets it, and we have written a guide to each one: how a page reads it, what each browser does about it, and what this site keeps. Every line of the table repeats a fact from one of those guides, with its source there. Where we have not checked a browser, the table says so.
Four browsers, reading by reading
What a page you open is given, with no prompt, in each browser's normal settings. "Private" means the browser's private or incognito window.
| Reading | Chrome and Edge | Safari | Firefox | Brave |
|---|---|---|---|---|
| Graphics chip | The exact name | "Apple GPU", the same for every Apple device | A similar model from about 131 groups | One name for every Brave user (since 1.93) |
| Screen size | The real size, private windows too | The real size; private: the window's size instead (since 17) | The real size | The real size |
| Fonts you installed | All of them can be tested, private windows too | Hidden: only the system's fonts | All of them; private: hidden (since 118) | A random selection, different on each site |
| Languages | The full list you set (once shorter, in a private window on an Android phone) | The list you set | The list you set | Your first language only |
| Battery | Level and charger, live | Nothing, ever | Nothing (since 52, in 2017) | Not checked |
| Audio test | The real result, the same every time, private windows too | Real; private: a little noise (since 17) | Real; no change documented | Altered per site and per session |
| Canvas drawing test | The real result | Real; private: a little noise (since 17) | Real; private: protected (since 120) | Altered per site and per session |
| Autofill | Fills fields you cannot see; the menu shows only your name and one line of address | Fills them too; the menu can show the full list first | Fills them too; the menu names every kind of detail | Not checked |
| Network address and time zone | Given by every browser. A VPN or Tor changes the address; no browser setting does. | |||
| What you do on the page | Pointer, scrolling, clicks, selection, leaving the tab: given by every browser. Reading the clipboard is not: Chrome and Edge ask, Firefox and Safari show a Paste button. | |||
Sources, one per line of the table: the linked guide for each. The canvas line: WebKit, "Private Browsing 2.0", 16 July 2024; Mozilla's Firefox 120 release notes, 21 November 2023; Brave, "Fingerprinting defenses 2.0", 18 May 2020. Our demonstration does not take a canvas reading; the line is here because trackers do.
Browser by browser
Chrome and Edge
They hand over the most, and a private window changes almost none of it. A page gets the exact name of the graphics chip, which says roughly how old and how expensive the machine is; can test for every font you installed; reads the battery's level and whether the charger is in; and gets the same audio result every time. When we ran the demonstration's audio test in Chrome, three times in a normal window and three in a private one, all six gave the same number. Edge is built on the same engine and gives the same readings; we have not checked its own private mode or its tracking prevention, and claim nothing about them.
Safari
Safari hides the most about the hardware: every Apple device is "Apple GPU", only the system's fonts are visible, and the battery has never been offered to pages. Its private windows, since Safari 17, go further: the screen is reported as the size of the window, and drawing and audio results carry a little noise, so they stop being the same number from one visit to the next.
Firefox
Firefox rounds the graphics chip into one of about 131 groups (a Mozilla engineer counted 83,705 different names before
the rounding), and has given pages nothing about the battery since 2017. Its private windows hide the fonts you
installed yourself and protect the canvas drawing test. It has a stricter setting, resistFingerprinting, off
by default, which goes further; the table is about the defaults.
Brave
Brave changes the most by default, in every window: one graphics name shared by every Brave user, a random selection of fonts that differs from site to site, only your first language, and audio and drawing results altered with a seed that changes per site and per session. It is built on Chrome's engine, but where we have not checked Brave's own behaviour, as with the battery and autofill, the table says so rather than guess either way.
What that means if you are choosing
- No browser hides where you connect from, or when. The network address and the time zone reach every site in every browser. The address usually points to a city; the location guide explains how far that goes, and how the time zone catches a VPN.
- Hiding helps most when many people give the same answer. Safari's "Apple GPU" and Brave's single name work because millions of browsers say the same thing. That is also why this site still recognises a returning machine in those browsers when the network address and the screen match: the generic name goes into the key like any other (where that fails).
- A private window is a different thing in each browser. In Chrome it changes what is stored on your machine, not what a page can read. In Safari and Firefox it also changes some of what a page can read.
- What you do on a page is given by all of them. No browser setting stops a page seeing your pointer, your scrolling or the form you fill in, short of turning scripts off.
What this site does with whichever you use
The demonstration takes what your browser offers and nothing it withholds: in Safari it is told "Apple GPU" and says what it can from that; in Firefox it never sees a battery. It recognises a returning machine by a one-way hash of four things, the network address, the browser's description of itself, the graphics chip's name and the screen in real pixels, which is why a Safari private window, with its window-sized screen, is usually a stranger to it. What it keeps, for how long and how to erase it is on the door and in the privacy policy; this page runs no script and sets no cookie.

Open the demonstration in the browser you use, then in another, and compare the receipts. It runs scripts and sets cookies; this page does neither.
Every reading, not only these eight, is on what a website can see about you without asking.
Short answers
Which browser tells websites the least about you?
Of the four we compared, Brave changes or hides the most by default: one name for every graphics chip, a random selection of fonts, only your first language, and audio and drawing results altered for each site. Safari hides the most about the hardware, and its private windows add more. Firefox hides the battery and rounds the graphics chip, and its private windows hide your own fonts. Chrome and Edge hand over the most.
Does any browser hide my network address or my time zone?
No ordinary browser does. Every website you visit receives your network address, which gives away a rough location, and any script can read the time zone your clock is set to. A VPN or Tor changes the address; the browser on its own does not.
Is Chrome incognito more private than Safari private browsing?
Not towards the websites you visit. In Chrome, a private window gives a page the same graphics chip, screen, fonts and audio result as a normal one. Safari's private windows, since Safari 17, report the window's size as the screen's and add a little noise to drawing and audio results.
Is Edge the same as Chrome for privacy?
For the readings on this page, yes: Edge is built on the same engine and hands a page the same things. We have not checked Edge's own private mode or its tracking prevention settings, so we claim nothing about them.
