This preference controls whether authors are allowed to specify animations
without a 0% or 100% keyframe.
We intend to ship this but it isn't implemented yet (needs a follow-up) but this
preference acts as a safeguard in case we discover we need to disable it once
it's implemented.
There don't seem to be any drawbacks to this; tested for the past month disabled
and there have been no issues with any sites visited. Adoption seems very low.
Since these are just interpreted comments, there's 0 impact on actual code.
This removes all lines that match /* vim: set(.*)tw=80: */ with S&R -- there are
a few others scattered around which will be removed manually in a second part.
This is just a clean port of 1322191 and follow-up 1325970. It really seems to add create a new way to access existing code relating to block formatting and floating elements rather than implementing new functionality, and it is mercifully straightforwards.
Unless a user is debugging media errors, this detail is unnecessary to report
and could include sensitive data which could be abused by third-party
requesters. This aligns it with the standard success/error paradigms in normal
browsing situations.
This is not very "clean," and is mostly done in the same sloppy way as Emilio did it because that's basically the only way you can do it. Note well that this does NOT actually turn off everything I've done in a clean fashion like ifdefs would. For instance, the Explicitly Enabled flag is still present, but is now always false because the only condition that can set it true is behind the pref and therefore inert when this pref is off. Also, because the arguments of SetDisabled have changed, my modifications to SetMozDisabled must be present regardless of whether the pref is on or off. What I have done is turn off the actual reflection of the disabled attribute in Disabled and SetDisabled, as well as in AfterSetAttr.
However, turning the pref off seems to restore more or less our old behavior, though there may be subtle differences unlike with an ifdef since this is, unfortunately, not an exact science and I can only turn off changes that happen within individual functions and not changes in how functions interact with each other.
This is apparently used for fallback selection and if available it is "assumed"
Shadow DOM is also available, while this is a utility function.
Webcompat is a nightmare sometimes.
These should all be spec-compliant and were (for release-trickling of features)
arbitrarily disabled by Mozilla at our fork point. There's no real reason to
keep them disabled since they are used in the wild.
This removes the (default disabled) node.rootNode readonly attribute
and replaces it with a node.getRootNode() function per WhatWG
spec discussion.
