Thorin-Oakenpants · 2024-12-26T02:33:50Z

changed

pref("security.pki.crlite_channel", "all"); // prev: "specified"

https://hg.mozilla.org/integration/autoland/rev/48d760ec3a63

previous options

# - "all" => filters that contain all revocations,
# - "specified" => filters that contain revocations with specified reason codes,
# - "priority" => filters that contain high priority revocations.

new options

# - "all" => bloom-filter cascades that contain all revocations,
# - "experimental" => clubcards that contain all revocations.

there's actually a new one = experimental+deltas which nightly has changed to 1927598

anyway, this seems like a step up, from specified to all - just wanted to check we weren't missing out :)

pref("browser.theme.native-theme", false);

For Linux/MacOS this defaults to true.

And where we are it, with non-native-theme there is widget.non-native-theme.use-theme-accent=true and ui.use_standins_for_native_colors=false (has an RFPTarget). This looks like a lot fingerprinting potential under Linux with its hundred different themes.

body = document.getElementsByTagName("body")[0]
body.style.backgroundColor = "Highlight" 
getComputedStyle(body).backgroundColor

https://arkenfox.github.io/TZP/tests/csscolors.html - not all css4 colors are protected by RFP (but some are)

Have you already written a test for everything? Or are there some secret untested Yeti, dwarfs, ...?

RFP basically covers a bunch of those 64 colors in the PoC (there used to from memory almost 100 - chrome has 40) - it also allows using user-set or system set colors for e.g. accent, visited link, link - but returns a hardcoded color when asked

and we (TB/AF) use browser.display.use_system_colors = false

what we want to do in future is hardcode in some "themes" (for lack of a better word) for accessibility and consistency

I have added 53 new metrics to TZP in the last 18 months - I have about another 50 to go - some you have never seen .. lots of yak-shaving and a few yetis

pref("browser.theme.native-theme", false);

For Linux/MacOS this defaults to true.

this is false on windows. AFAICT this pref is about styling the chrome, not web content
