  > Websites already break often with the strictest protections enabled, adding a "super duper strict protections" mode will just lead to bug reports. That’s what I‘m saying. They already break because of other effects of the strict settings, so what is the benefit of leaving resistFingerprinting turn off? > There is no full immunity against fingerprinting. There is 0 immunity if you don’t even try. Strict means, do what you can, not do somethings strict other not so strict and others ignore completely. Don’t call it strict if it isn’t strict

    The description in Firefox state: > Stronger protections that block more trackers, but may cause some sites to break. That seems very reasonable to me. Anyone who wants more than that can turn on resistFingerprinting and live with the consequences.

        (n.b. I own these features in Firefox) There are three levels of protection: - ETP Standard (see [0] for the latest improvements we rolled out) - ETP Strict (we're working on things in Bugs 2036879 specifically this issue, 2037260, and more generally 2036786) - Resist Fingerprinting (RFP) These levels are something akin to "Wash your hands after using the subway", "Wear a mask on the subway", and "Wear a level B hazmat suit on the subway". "people already expect sites to break, so why holding back?" - because the breakage is so severe, and people _don't_ associate that breakage with the setting they made. There are bug reports all over the internet proving it, here are some examples [01-4]. The protections we deploy in ETP Standard and Strict are calibrated to provide as much protections as possible while keeping the internet usable, and we're working fulltime on improving them.

          first off, thank you for your service. second, would it be possible to make RFP appear as an extension like uBO, where it suggests sites to allow-list, or hints that the page might be broken and asks if you want to disable RFP? I'm more tech savvy than the average user, admittedly, but I've learned this pattern for uBO.

            For a time RFP - by itself - could be enabled by web extensions. (It might still be possible, I don't recall if we removed it.) But it's a footgun because it became even easier for people to enable it by accident. I can point you at a few things you could do if you wanted to pursue this: 1) We have a dev extension https://github.com/mozilla-extensions/fingerprinting-protection-debugger https://github.com/mozilla-extensions/fingerprinting-protect... that lets you enable/disable individual fingerprinting protections. We use to debug why something is broken. 2) granularOverrides allows you to enable/disable individual protections for a given website. If you wanted this, you could go read https://docs.google.com/document/d/1FywogzvkWupoUoz4PcCp9nNd6aKOwBN-c2zRu2Xof9Y/edit?tab=t.0 https://docs.google.com/document/d/1FywogzvkWupoUoz4PcCp9nNd... ; then made an extension that made it easy to edit granular overrides (you couldn't directly set the preference, but you could produce the json you could copy/paste into the pref). You could do stuff with lists if you want. (Somewhere there was a FF fork that had a pretty impressive granularoverride list itself...) You'll be in this awkward spot where you don't have all the permissions to do what you want to do directly, but you can get yourself about.... 40 - 60% of the way there? I would like to find a way to support power users while not making the problem worse (In https://ritter.vg/blog-telemetry.html https://ritter.vg/blog-telemetry.html I describe that the 'confused users think FF is broken' problem got so bad management wanted to just disable RFP entirely, but I was able to show that these users are a very vocal minority and the problem is not as bad as it seems) while also not giving myself a maintenance burden but... maybe there a path forward where this dev extension - that can do things normal extensions can't - could potentially get more functionality...?
