updates Meet the browser: Firefox Next

[The_Decryptor Veteran]

Yeah, Firefox doesn't support Media Source Extensions for H.264, which is what YouTube wants.

YouTube is moving towards DASH for everything, and that needs MSE for pure HTML/JS based playback.

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.

Ditto that. My system falls in the "decent specs" category, not running four GPU's or anything but decent.

Firefox (Flash) was giving me ~38FPS.  Visually I didn't really notice much of a difference, not going to switch over it but *shrug* numbers don't lie.   Chrome and HTML5 was the full 60, frame dropping was at a minimum. On the plus side, CPU usage on both Chrome and Firefox were near zero while running both videos at 1080.. it's not being starved for resources or CPU time.  Flash obviously needs some more work/refinement.

Chrome:

I was actually getting the same 38-48fps value on both of my systems, I wonder if it's some odd Flash bug.

No way in hell a 9400M and a GTX 570 should have the same performance at H.264 decoding.

Edit: 35fps, close enough.

For YouTube and MSE have you tried enabling media.mediasource.enabled via about:config and forcing the HTML5 player? The Battlefield Hardline 60FPS trailer works fine there using HTML5/VP9/MSE in Nightly.

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.

doesn't seem to be a firefox issue, I get tons of dropped frames when viewing that video in chromium. Only plays smooth 60 fps for me when using google chrome/html5 player. And this is on my gaming desktop (i5-2500, 16gb ram, amd 280x)

 

Flash is terribly optimized, who would have thought  :rofl:

Enabling that appears the 1080 option but it doesn't start(At any resolution), using estable version(30)

Thought so, though using that flag *might* work with Firefox 31.

Yeah seems like it might just be flash, but then TwitchTV has issues on Firefox with 60FPS streams while Chrome/IE don't and Twitch still uses Flash. Also, high polling rate mice make the stream lag when mousing over the video for whatever reason, and this also happens on Youtube when using the HTML5 player, but not the Flash one (!?). SOMETHING is not working right, somewhere, that's for sure.

Loop landed in the latest nightly, at least the UI code for setting up Loop sessions did.

Finally we can do this:

looks like all the search plugins need to be updated to support that feature or it could be coded better on Mozilla's end.  Selecting DuckDuckGo disables the menu.

 

Is there a way to increase the number of thumbnails on that page without an addon?

Go to about:config and change these two preference to whatever number and in which you want to increase.

 

 

browser.newtabpage.columns

browser.newtabpage.rows

What the post above me said. And if you want to make them wider, or whatever, here's the Stylish script made by some member from this site. I cannot recall his nickname though.

@namespace url(http://www.w3.org/1999/xhtml);



@-moz-document url("about:newtab") {

    

.newtab-cell {

  height: 110px !important;

  width: 450px !important;

}



}

Thanks for the reply.  I'm on the nightly so the about:config entries don't work.  The page seems to adjust the number of thumbnails based on the size of the window and is totally ignoring those settings.

 

Apparently, the only reason that the new tab tools addon works for the nightly is because they are using the older page code.

I am also on Nightly and they work fine for me...

[+Neyht Subscriber²]

At lower resolutions (or window size) it fits what it can on the screen, but your right it does honor those settings.  Guess I just want to make the thumbnails smaller then.

 

 

...also this

 

 

duckduckgo.xml

 

I threw something together to make the duck duck go image show on the new tab page.

 

Thanks for the help guys, that's one less addon I need.

Some Insight:

- CSS Font Loading API relevant Work In Progress is happening: https://bugzilla.mozilla.org/show_bug.cgi?id=754215 ; https://bugzilla.mozilla.org/show_bug.cgi?id=1031187
- Media Source Extension work in progress since now Youtube heavily rely on it so Mozilla is dragging its feet for quick support.
- Mozilla started to use heavily Coverity Static Analysis tool in conjunction with Clang static analysis tool and LSAN from Google to fix leaks and security bugs.
- Several dead code cleanup happened in back few days, JS Debugger version gone, XPIDL stuff relevant to DOM Bindings gone since now WebIDL is future and another thing which I forgot now... :-) this as well: https://bugzilla.mozilla.org/show_bug.cgi?id=933019

Haha, it's about time.

Haha, it's about time.

 

Actually due to its ongoing flux standard, I think its quite debateable and several things regress due to it. Video Playbacks on other sites.

[The_Decryptor Veteran]

One issue they've run into is that their existing framework to play videos didn't work well with what MSE wanted. Their previous setup was basically "Hey OS, here's a video file, play it", while MSE deals with chunks of streams that can differ in quality/resolution and the OS libraries they were using didn't really like that.

 

So they're in the process of integrating the Android MP4 demuxer into Firefox, and wiring the platform decoders up to that (And for OS X as well, finally getting H.264 playback on Macs), but that code is currently extremely buggy (With the right prefs you can enable it for MSE, and it'll instantly crash)

 

WebM works fine (Which should be enough for YouTube), but the YouTube player doesn't do bandwidth adaption right due to a lame spec/browser issue IIRC (The DOM events spec allows for a timestamp of "0", which is useless. But Mozilla is in the process of changing to accurate times, which a lot of stuff doesn't parse right, but stuff is no more broken than it currently is)

 

Edit: And all the changes helps the OpenH264/EME work, since they're being plugged in like the platform decoders.

If someone is noticing weird behavior in Firefox Nightly 33 link and page Ctrl+clicking, its due to this change to match Opera Presto like text selection behavior with little improvements...

I wondered what was causing that, annoying since I don't have middle click on this trackpad, but if I can select text inside a link now I'm ok with it.

Have you tried 'clicking' with both mouse buttons at the same time? Works on my trackpad.
