  • gfx.offscreencanvas.domain-enabled looks interesting (at least knowledge wise), but I need to educate myself on how offscreenscanvas is implemented and https://bugzilla.mozilla.org/show_bug.cgi?id=1422862#c5.
  • for the record network.http.useragent.forceVersion doesn't override the RFP-set user agent.
  • I wanted to see what changes with reader.improvements_H12022.enabled = true, but it looks the same to me :-(

offscreen canvas doesn't impact fingerprinting (besides the API being enabled or not), as JS can't read back any info AFAICT, and upstream tom ritter has his eye on it anyways

  • FF96 1735874 Fix broken resist fingerprinting with OffscreenCanvas on worker threads
  • FF97 1736177 Add initial implementation of OffscreenCanvas + WebGL

https://bugzilla.mozilla.org/show_bug.cgi?id=1422862#c5 (tom ritter)

Yes, this sounds like we misunderstood the feature when we initially filed this bug (so as not to forget about it.) If there is no way for an OffscreenCanvas to actually give its rendered content via an API (like there is for canvas through e.g. toDataURL), and all it can do it stick it into a canvas (where permission prompts work) or another object that can't be read via Javascript (like an <img> tag) - then we are fine here

TBH I don't understand all of this yet either (it also involves webGL + workers) but I did test

  • gfx.offscreencanvas.enabled = true
  • gfx.offscreencanvas.domain-allowlist = "*.canvasblocker.kkapsner.de" (not sure if this is needed)
  • CB canvas test page

I get (offscreen and offscreen worker)

  • Firefox: Error while computing: context.fillText is not a function
    • this is on nightly 101 and it doesn't seem like it's hooked up yet - IDK, not worried about it (yet)
    • or maybe I'm not flipping the right things or using the right tests?
  • Blink: no errors

I wanted to see what changes with reader.improvements_H12022.enabled = true, but it looks the same to me :-(

Thought the same at first, but after resetting reader.color_scheme to the new default of "auto" (was set to "dark" before) reader mode set the preference to "light" with reader.improvements_H12022.enabled set to the default false, and leaves the pref untouched and shows the dark theme with it set to true. So for new installs I guess you'd need to turn the pref on to get the expected color scheme now, at least I did on my Arch Linux KDE environment.

pretty sure reader view doesn't allow JS to execute (but I'll check) but FYI

  • load test page
  • flip to reader view
  • open console
  • paste the following snippet
console.log(document.body.classList.value, document.body.getAttribute("style"))

example

  • we could even check for aria elements to detect if that is enabled
    example
