Intent to unship: HTML scoped style sheets (

HTML scoped style sheets is a feature that allows the effects of style sheets to be scoped to a subtree of a document. Support for this feature was introduced first in Chrome 19 behind a flag (in mid-2012) and in Firefox 21 without a pref (in mid-2013). Since then, Chrome removed their

Yes. I use Instruments on Nightly builds extensively. It would really be a loss to lose this functionality. I think it's important to weigh the performance improvements that we get from easy profiling against any advantage we get from stripping the symbols. -Jeff On Mon, Jun 19, 2017 at 6:07 PM,

Profiling nightlies on Mac - what tools are used?

Hey all, The build peers are looking to change the way that nightlies are created on Mac as we switch to cross-compilation. Specifically, we're looking at stripping the nightlies to avoid an as-of-yet undiagnosed performance discrepancy vs native builds[1], but also to make the nightly
