After bug 1251161 landed, we turned CSS mask image on by default on all platforms. It has been developed behind the MOZ_ENABLE_MASK_AS_SHORTHAND compile flag. Chrome is already shipping this in version 29.
(Original plan is to turn it on by FF 50, delay it to FF 53 is because of some performance work, such as bug 1234485) Related Bugs: META: https://bugzilla.mozilla.org/show_bug.cgi?id=1224422 Blockers: https://bugzilla.mozilla.org/show_bug.cgi?id=1251161 Spec: https://drafts.fxtf.org/css-masking-1/ Target release: Firefox 53 (current Nightly). _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
