updates Meet the browser: Firefox Next

[Syanide]

Sometimes I open an image in a new tab and the tab titlebar area gets totally botched when I switch focus to the tab, losing the background color for the most part. Anyone else gets this? Only happens if an image was open in it.

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

Nah, that's right click for me, don't think the driver supports sending a middle click.

Firefox Multi-process architecture roadmap

    July 18, 2014 - Milestone 1: make E10s usable for average Nightly users but is not enabled by default.
    July 21, 2014 - Firefox 34 development begins. Mozilla wants to use the six weeks that follow to get Nightly users and add-on developers to test e10s and especially add-on compatibility.
    September 1, 2014 - Firefox 35 development begins. Mozilla plans to reach Milestone 2 in this development period. When Milestone 2 is reached, Electrolysis is at a point where it can be enabled for Nightly users.
    October 13, 2014 - Firefox 36 development begins. This is the version of the browser where Firefox's multi-process architecture will be moved from channel to channel (Nightly > Aurora > Beta > Stable) so that it is released to the stable channel of the browser on February 16, 2015

[The_Decryptor Veteran]

Pretty sure it's on the roadmap, but I hope we get APZC and tiling on desktop before e10s.

Google enforces HTML5 use on YouTube for Firefox 33

DXVA2 just like IE11, I hope?

[The_Decryptor Veteran]

Firefox has done DXVA decoding for quite a while, bigger issue is that YouTube wants Media Source Extensions, which doesn't currently work.

Upside is that Window users at least get 720p H.264 for the fallback case, but OS X users (i.e. me) get 360p WebM (Y)

Edit: yeah, Firefox has used DXVA2 since version 23.

Font refactoring work in progress & will land next cycle [34]

 

• Fonts are only read once from disk while in use (they are discarded if the reference count reaches zero, however). This saves memory and prevents unnecessary reading from disk.
• It will be easier to add web font support, as all fonts are created and managed in a single place and the entire pipeline ensures that only one in-memory copy of font data is required.

An overview of how the pieces fit together:

FontTemplate - A structure containing everything that
is required to create (and select) font handles. This
structure is shared among all matching font handles
(via Arc).

FontTemplateData - A platform specific structure that
contains the actual font data inside a template (this is
a byte array on Linux/Android, CTFont on Mac).

FontHandle - An opaque, platform specific handle to
a font instance. Each FontHandle contains an Arc<>
reference to the FontTemplate it was created from.

FontCache - This is a separate task, that is responsible
for loading and caching FontTemplate structures. There
is one FontCache per constellation. It is only ever accessed
via the FontContext described below.

FontContext - This is the public interface to the FontCache
and is used by the layout and render code to create font
handles. These must not be shared between threads. There
is typically one FontContext per thread/task.

media.peerconnection.video.h264_enabled and  set it to true.

 

Mozilla had quite the discussion about how to handle this delicate matter. For now, it seems to favor the following decisions:

• The video codec is listed under Plugins in the Add-ons Manager.
• Users will have options to activate or deactivate it there.
• Click to play support wont be implemented.
• Automatic updates will be supported.
• Target are all supported desktop platforms.

even though OpenH264 is listed under plugins, it is not a standard plugin, Mozilla files it under Gecko Media Plugins

GMP is a special purpose extension point for authorised 3rd party codecs and EME (Encrypted Media Extensions) CDMs (Content Decryption Modules).

Besides that, it is a component that gets downloaded and installed directly by the browser even though it is not maintained by Mozilla but downloaded from Cisco instead.

[The_Decryptor Veteran]

The GMP plugin interface is generic enough to allow for any real codec to be slotted in (Daala could be distributed that way), but it's also sandboxed to hell and back and Firefox won't use any random module, it has checks in place to only allow specific ones (To avoid the situation with plugins where sites can prompt users to download and install them)

The Adobe DRM module is going to plug in the same way (Since it's a H.264 decoder that functions specifically on encrypted streams, so all the demuxing stuff is the same), although that also requires Firefox to limit what the user can do to the resulting decoded frames.

[Excelsis]

With Youtube enforcing HTML5 use, I've been seeing some videos where the only choices are 360p and 720p, when I know 480p/1080p are also choices. When can we expect this to be fixed? I thought having h.264 would do it, but I've enabled it and those same videos still only have 360p/720p.

[The_Decryptor Veteran]

You also need to enable Media Source Extensions and tell Firefox to enable H.264 support (Hidden pref I can't remember the name of), and it'll most likely crash instantly (Or you'll get one stream playing, blank video, etc.)

It's apparently been done on Google's end so that Mozilla can test MSE in a production environment, it's only enabled for Nightly users.

[Excelsis]

I am running Nightly and enabled MSE. Still happens. It seems to be videos that would have ads when using the flash player though. Been waiting on this for awhile though, so it's better than nothing.

[The_Decryptor Veteran]

Only getting 360p and 720p means it's not using Dash, which means it's not using MSE and falling back to plain H.264/WebM. Does this page work for you?
