-- In-Content UI is disabled for Firefox 32.

-- YARR (Yet Another Regular Expression) code ported from Webkit has been removed from m-c (mozilla central) code base and Irregexp (from v8) replaced YARR.

-- After shifting to mozilla::pikx certificate validation, devs are planning to rip out NSS based code from M33.

-- Currently UTF-16 and ASCII strings conversion to UTF-8 is happening in mozilla JS side, it will improve performance and memory usage. v8 engine of Chrome already do this. Its Latin1 strings project.

Landed

Mostly performance boost

 

Smoother Scroll

  • Bug 894128 (windows scroll is not smooth) - new Intel driver from latest windows updates improves our rendering performance with Intel iGPU considerably - by ~x2-x3 factor (both with/without OMTC). Clearly visible and apparent at TART numbers, scrolling numbers, customize animation, etc. Posted some new info and measurements with the new driver.
  • Bug 1013262 (windows OMTC regressions) - was about to be dismissed with "we haven't heard users complaining", asked milan for some more explicit decision, he responded good enough (and without changing the course of action).

Newtab page speed & animations improvements

  • Bug 1019990 (newtab preload should also preload the content - to make the search bar and hopefully newtab in general to fully preload and therefore improve the visible glitch and tab animation) - feedback that Yahoo still flickers even with preload

 

 

Done

 

Fixes for memory consumption & Speed

  • Bug 1007723 - Telemetry (?) is causing a high memory consumption and lagging on browser startup - landed
  • Bug 936617 - Add talos regression test for "cold" startups - ready to deploy
  • Bug 1021128 - Data missing from main-thread I/O dashboard - job is running on local AWS machine
  • Bug 987728 - Avoid main-thread IO for {profile}\localstore.rdf - work in progress

Judging from this bug landing: https://bugzilla.mozilla.org/show_bug.cgi?id=1022856

 

I guess Firefox is going with Microsoft Bing Translator for other languages content translation..

Ehh, it's not really a fix, more of a relaxation of a fix (NTLMv1 is broken, so Mozilla disabled it, turns out people were relying on it so as a compromise they enabled it for TLS connections, because running an insecure cipher over a secure connection is stupid, but still secure)

Complicating the issue is that on Windows, Firefox uses the OS libraries (So NTLMv2+), on OS X/Linux it tries to use system components (Which could be anything, or nothing), and if all that fails it falls back to the inbuilt NTLMv1 only library, that's what got disabled.

So, with Youtube announcing (and demonstrating) 60 FPS videos on their website, when can we expect Mozilla to fix their shoddy Flash support?

TwitchTV has supported 60FPS for quite a while now and it has always dropped a bunch of frames. If you move your cursor over the video it makes it struggle to even maintain 30 FPS, let alone 60.

Same for OneDrive's web video player. And now with Youtube's 60 FPS videos, it's almost dropping 50% of frames, negating the bump in frame rate.

 

And I'm pretty sure I'm not the only one as others have mentioned the same issue of dropping frames on the comment section of Youtube's 60 FPS videos that were posted.

 

Here's one of the videos for anyone interested, by the way.

Flash sucks, nothing new.

Firefox supports hardware accelerated drawing surfaces for plugins (Which lets them render as fast as the screen refresh rate), it's up to them to use it.

Tried that video and saw frames dropped with Flash @ 1080p. Switched to HTML5 in YouTube Center Settings to test and had only 720p option for the video.

Anyone familiar with YouTube Center and knows what to do to get 1080p option in HTML5 player?

YouTube requires Media Source Extensions for the high quality options, it's currently only enabled for specific formats in Firefox.

The video posted before drops frames on both my Mac and PC (Even though the PC is vastly more powerful), Flash wasn't even using hardware rendering on my PC, and even in full screen mode (Where it bypasses Firefox completely) it was dropping frames, Flash is just odd.

Firefox itself has no issue playing 60fps video, not a single dropped frame on my PC.

chrome uses vp9 codec for the 1080p 60fps video. It used 50-60% cpu on my core i5 1st gen laptop 430m apu in html5 mode. Got tons of dropped frames.

With Chrome you can put it @1080, so i guess its Firefox problem
