Based on Mozilla bugs 1119128, 1285533, and 1421964.
gfx.font_rendering.fontconfig.fontlist.enabled is no longer available.
gfxFontconfigUtils.h still exists, and will be removed in another commit. Just
need more research on bug 1385029.
Tag #1862
- Block slot elements from being matched by ::slotted
- Ensure ::slotted() is serialized as a pseudo-element
- Add pref to control whether the pseudo-class is enabled
This ensures that the content type is also determined when opening JAR channels both synchronously and asynchronously. Current m-c modifies only the async portion, while the mentioned commit below modifies only the sync portion. This commit does it for both.
Partially based on 425677ada7380f7c592dd01ddfbc9631ab2038a0 and bug 1757604.
Speech recognition was removed a while back. The pref is just leftover.
Having the TTS API available will provide some accessibility benefits
for users, so flip that on while we're here.
This modifies selector list parsing to accommodate being "forgiving". Aliases for the :is selector's former names were also included. Note that the older and prefixed variant `-moz-any` remains unforgiving.
Controlled by image.animated.decode-on-demand.threshold-kb, default 256MB
Includes squashed bugfixes/regressions:
- m-c 1444537: Shutting down the decode pool should make animated decoders bail early
- m-c 1628606: Make sure to mark the surface cache entry available before sending the frame complete notification
- m-c 1502275: Skip recreating the decoder after redecode errors if an animated image is reset
- m-c 1443232: Don't insert frames into our AnimationFrameBuffer that we consider in error and unusable
Includes squashed changes of:
- m-c 1317907: Refactor FrameAnimator::GetCompositedFrame to be a bit simpler
- m-c 1351434: bugfix
- m-c 686905: Enable the pref image.mem.animated.discardable to allow discarding of animated images
We may eventually want to make this permanent in the front-end of
Pale Moon for privacy reasons.
Disabling this to avoid usage expecting changed spec results.
This will prevent the keypress DOM event from firing on keypresses
that do not produce printable keys (e.g. editing nav keys) in content.
This should not affect any chrome events that are in use.
Event dispatch can be re-enabled if necessary with the added pref.
This allows us to use a greater rendering depth for exceedingly-deep DOM trees
in layout, better matching what mainstream browsers are capable of. Note that
for 32-bit Windows the stack size MUST be set to larger than the default or Bad
Things Will Happen™ - we use 1.5 MB for this as a carefully-tuned value.
This needs to be capped specifically for JS use because some JavaScript
obfuscators deliberately trigger stack overflows and would lock up the browser
otherwise as long as there's still stack space to abuse. For web compatibility
we therefore limit this to 2MB in JS only (3x for ASAN) while still allowing
a greater depth for the layout engine.
Since there really is no need to add file detection logic to the updater
if updating through AUS is old->new only anyway, replacing bzip2
handling with xz handling is fine, instead of adding it.
Considering the far superior compression of LZMA and MAR not being
a common archive format anyway, let's just K.I.S.S. it :)
The removal of this preference was botched, all other surrounding plumbing changes appear to be working okay. The ability to use prefs to control this stylesheet might be useful in the future, so perhaps this is one of those "if it ain't broke, don't fix it" bugs where leaving well enough alone in the first place would have been the best choice.
This PR passes all current tests for this feature, and implements the "prefers-color-scheme" media query as an enumerated keyword that is controlled by an integer preference.
Currently, the possible options are 0 to see a website's fallback code and essentially behave like this isn't implemented (our current behavior), 1 to express a preference for a light theme (the default for spec reasons), and 2 to express a preference for a dark theme. Over time, this list may expand to include other preferences like a preference for a sepia theme or something, and this leaves us prepared for that future.
