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
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.
