Originally part of bug 768067, but didn't happen there.
Created attachment 8791582 [details] [diff] [review] 931389-remove-mozDash-and-mozDashOffset.diff Since the unprefixed versions of these features have been in Firefox since version 27, the MDN page for the standard version has noted that they're deprecated since at least July of last year, and no addons on DXR are only using the prefixed versions, I think it's probably safe to go ahead and remove them now. Here's a patch which does so. Try seems fine: https://treeherder.mozilla.org/#/jobs?repo=try&revision=035996f88667 Intent to unship: https://groups.google.com/forum/#!topic/mozilla.dev.platform/UIudMABegcY
Comment on attachment 8791582 [details] [diff] [review] 931389-remove-mozDash-and-mozDashOffset.diff Review of attachment 8791582 [details] [diff] [review]: ----------------------------------------------------------------- I'm ok with this, but let's give dev-platform a little more time to raise any possible objections.
I still haven't received any feedback on the dev-platform thread, George. Would you still like to wait a while longer?
Nope, let's go ahead with this.
Created attachment 8797719 [details] [diff] [review] 931389-remove-mozDash-and-mozDashOffset.diff Alright then. Here's a rebased version of the patch. A fresh try run* seems fine, so I'm carrying over r+ and requesting check-in. * https://treeherder.mozilla.org/#/jobs?repo=try&revision=dbc5436cc4cb2f370c38806703dda9126f64f00d
Posted the site compatibility doc: https://www.fxsitecompat.com/en-CA/docs/2016/canvas-2d-mozdash-and-mozdashoffset-have-been-removed/
The webidl changes need DOM peer review.

I think that since these have been marked for obsolescence for so long, have been removed completely, and were Gecko-only anyway, they can be removed from the docs. I've removed the mentions from https://developer.mozilla.org/en-US/docs/Web/API/CanvasRenderingContext2D#Non-standard_APIs I've also added a note to the Fx52 release notes: https://developer.mozilla.org/en-US/Firefox/Releases/52#Others
