      You can also use canvas blocker add-on.

      Use their containers (firefox multi-account container add-on) feature and make a google container so that all google domains go to that container.

      If you want to get crazy, in either set in about:config or make yourself a user.is file in your Firefox profile directory and eliminate all communication with google. And some other privacy tweaks below.

      google shit and some extra privacy/security settings

      Google domains and services:

        I’m still trying to wrap my head around fingerprinting, so excuse my ignorance. Doesn’t an installed plugin such as Canvas Blocker make you more uniquely identifiable? My reasoning is that very few people have this plugin relatively speaking.

          Iirc, Websites can’t query addons unless those addons manipulate the DOM in a way that exposes themselves.

          They can query extensions.

          Addons are things installed inside the browser. Like uBlock, HTTPS Everywhere, Firefox Containerr, etc.

          Extensions are installed outside the browser. Such as Flashplayer, the Gnome extensions installer, etc.

            Further: the Canvas API doesn’t have any requirements on rendering accuracy.

            By deferring to the GPU, font library, etc, tracking code can generate an image that is in most cases unique to your machine.

            So blocking the Canvas API would return a 0. Which is less unique than what it would be normally.

          Maybe if they can connect you to your other usage but it’s probably more of their resources and such a small % of the population that it isn’t worth the time to subvert? Idk just guessing here

        I use (and love) Firefox containers, and I keep all Google domains in one container. However, I never know what to do about other websites that use Google sign in.

        If I’m signing into XYZ website and it uses my Google account to sign in, should I put that website in the Google container? That’s what I’ve been doing, but I don’t know the right answer.

      Why does it do this?

      • Math operations in JavaScript may report slightly different values than regular.

      PS grateful for this option!

      I’ve used this. The only annoyance is that all the on-screen timestamps remain in UTC because JS has no idea what timesone you’re in.

      I get that TZ provides a piece of the fingerprint puzzle, but damn it feels excessive.

        And automatic darkmode isn’t respected, and a lot of other little annoyances. That’s why this is so difficult. These are all incredibly useful features we would have to sacrifice for privacy.

          Dark mode can be recreated using extensions, although the colors most likely won’t be as legible as “native support”.

          I don’t see why a similar extrnsion couldn’t change the timezones of clocks.

          Additionally, I don’t see why the server should bother with either (pragmatically) - Dark mode is just a CSS switch and timezones could be flagged to be “localized” by the browser. No need for extra bandwidth or computing power on the server end, and the overhead would be very low (a few more lines of CSS sent).

          Of course, I know why they bother - Ad networks do a lot more than “just” show ads, and most websites also like to gobble any data they can.

        It’s a nice feature for those that actively enable it and know that it’s enabled, but not for the average user. Most people never change the default settings. Firefox breaking stuff by default would only decrease their market share even further. And this breaks so much stuff. Weird stuff. The average user wants a browser that “just works” and would simply just switch back to Chrome if their favourite website didn’t work as expected after installing Firefox. Chrome can be used by people who don’t even know what a browser is.

      Please don’t enable this blindly. A lot of modern websites depend on a bunch of features which will simply not work with that flag enabled. Only do it, if you’re willing to compromise and debug things a bit
