Font Fingerprint Defender
Description from store

Font Fingerprint Defender is a lite extension that let you easily hide your real font fingerprint by reporting a random fake value and protect your privacy.

This add-on does NOT block the fingerprint, instead, it simply adds a small noise to the actual fingerprint and "renews" it every time you visit a website or reload a page. It is important to note that, this add-on does not have any settings or options to adjust. Simply add it to your browser and start surfacing the internet. If you want to test this add-on, please visit a website that show your fingerprint (i.e. webbrowsertools.com/font-fingerprint/). Every time you reload the page, you will see a new fake fingerprint.

This extension is made in collaboration with the author of "Canvas Fingerprint Defender":
https://chrome.google.com/webstore/detail/canvas-fingerprint-defend/lanfdkkpgfjfdikkncbnojekcppdebfp

Note 1: depending on your browser and platform, you may need to (Shift+Refresh) a web page to renew Font fingerprint.

Note 2: To report bugs, please visit addon's homepage (https://mybrowseraddon.com/font-defender.html) and fill the bug report form.

We need this extension to change the fingerprint only once for each new page load, and not on every page refresh.

Nobody's tracking you. You're just paranoid. Get over it. You're not valuable enough to track.

Essa extensão não está fazendo o que promete. Funcionava antes, agora não funciona mais. Eu testei muito usando o site " deviceinfo.me ". This extension is not doing what it promises. It worked before, now it doesn't work anymore. I tested a lot using the " deviceinfo.me " website.

I see that it actually WORKS!!! But it requires that Chrome browser is up to date and shouldn't be too old. Most people use outdated chrome browsers and need to update it.

AFAIK, it spoofs what it is supposed to. I dislike tabs opening with Font Fingerprint Defender (FFD) ads. FFD just opened the tab in the browser and first line says "Advertisement", and rest is all about FFD. I just spotted it, had I known when I clicked 'Report" was going to handed off to Google, I would have stopped there. WARN people when you're going to send them to the king of stalkers. I and I am certain others, use FFD as a defense against all the SMIRC ers and that does NOT preclude Google. Not donating, may just clean out FFD and make certain nothing left and then take a shower.

This is awesome for privacy and doesn't let businesses track you based on the fonts you have installed.

Works, but breaks css on some websites (for example gazeta.ru). Would be nice to have an option to whitelist particular sites.

Does exactly what it should do and claims it does. Tested at https://browserleaks.com/fonts and it spoofed both forms of font fingerprinting. I like that this is a one-exploit fix [well, TECHNICALLY it's two in this case] instead of a plugin claiming to spoof all forms of user fingerprinting, since new methods of that come up all the time. It's better to be certain that you have a particular weakness patched up because you have an extension that corresponds to it exactly, than to go without preventing a leak because you assumed it was included in some catchall extension but it wasn't. PS: Anyone who cannot figure out that they can click on the extension's icon and pick "Show|Hide desktop notifications" simply doesn't DESERVE to use this extension. Heh. Really, the developer should just turn this option off by default in this entire series of fingerprint defender extensions, since it's obviously the only thing causing unhappy feedback about any of them.
