Why YSK: Websites on the internet often try to uniquely identify your device, this extension attempts to prevent that and make it hard for them to do so.
Firefox’s built in “Enhanced Tracking Protection” already does a lot of this work for you, especially if you select “strict mode.” Go ahead and try this extension if you prefer. But remember to be selective with the extensions you add to your browser in general, as they also present an opportunity to introduce vulnerabilities.
I tried that and then one of those “how common is your fingerprint” websites said my fingerprint was unique. Literally fucking unique.
I think it was the EFF site.
Might have something to do with other extensions I have installed like Canvas Blocker, uMatrix, etc.
Fuck, even in Mull on my phone where I only have a few extentions installed: uBlock Origin, cookie auto delete, local CDN, and a cookie consent blocker.
As you suggested, I suspect it’s the rare combination of additional extensions that’s contributing to your uniqueness in a fingerprinting sense.
