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

When Mozilla announces such dates/version targets you always have to at least do +2, if not +3.

Latin1 Strings (UTF-8) has been now default enabled (https://bugzilla.mozilla.org/show_bug.cgi?id=1037871) for many stuff. It will bring memory efficiency and improvement in certain js benchmarks like ss-dna. It will also help in cleaning some dead code as well. Not to mention Chrome v8 JS engine also use UTF-8 strings.

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 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.

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.

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.

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?

http://dash-mse-test.appspot.com/dash-player.html?url=http://yt-dash-mse-test.commondatastorage.googleapis.com/media/car-20120827-manifest.mpd

Nope, not working. Getting this error in the console below the video player: Deregistering progress timer and Implausible duration from video element: NaN.

Tried a new profile, enabled MSE and h.264 and it still doesn't work. Tried again after downloading the latest Hourly and it's doing the same thing.

OpenH264 plugin just says "will be installed shortly" and i've set "media.peerconnection.video.h264_enabled;true", am I missing something. Using 64 bit nightly.

    • Microsoft making much needed change to Windows 11, 10 Patch Tuesday security updates by Sayan Sen Recently, Microsoft delivered its latest Defender patches for Windows 11 ISOs. These definitions are released from time to time alongside the general security updates available during Patch Tuesday. Speaking of Defender, the company has now announced another important change that affects how security updates are delivered to enterprise devices running Windows. According to a recent announcement, Microsoft Defender for Endpoint's endpoint detection and response (EDR) updates will no longer be bundled with the monthly Windows security updates or Patch Tuesdays. Instead the company is shifting delivery of these updates to Microsoft Update, bringing EDR servicing in line with several other Microsoft Defender components. If you recall, Microsoft last year moved PowerShell updates to Microsoft Update (MU) as well since it provides automatic updates for Microsoft products and services. Thus the move is intended to allow Microsoft to deliver EDR improvements and security enhancements independently of the OS's regular monthly update cycle; this should enable faster deployment of protection updates without requiring organizations to wait for the next Patch release. For those unfamiliar, Microsoft Defender for Endpoint's EDR capabilities are designed to help organizations detect, investigate, and respond to advanced threats across managed devices. Keeping these components updated is critical for maintaining protection against evolving attack techniques. The rollout has already began for Windows 10 devices in late May 2026 (last month) and Microsoft says it will gradually expand support to Windows 11 and the remaining supported Windows versions over the coming months. The company expects deployment across Windows 10 and Windows 11 to be completed by fall 2026 or around Q3 of this year. Once the transition is complete, EDR updates will be delivered through Microsoft Update using KB5005292, provided the required prerequisite updates have already been installed. Microsoft is also introducing a new Defender Update Service as part of the change. Following installation of the first update, devices will automatically create a new directory located at %ProgramData%\Microsoft\Microsoft Defender\Defender Update. Microsoft notes that restarts may occasionally be necessary in case of "rare" failure scenarios. For most organizations, the tech giant says no action will be required as long as Microsoft Update is already permitted within their update management strategy. Admins who rely on manually deployed update packages, however, will need to adjust their processes to ensure the new Defender update package is included. Microsoft also recommends reviewing internal documentation and notifying helpdesk and security operations teams about the updated delivery mechanism to avoid confusion during the transition. As a prerequisite, the tech giant notes that systems must be running Sense version 10.8798.25857.1000 or later and have one of the following Windows updates (or later) installed: Win11 24H2 KB5062660 (2025-07 Cumulative Update Preview) Win11 23H2 KB5062663 (2025-07 Cumulative Update Preview) Win11 22H2 KB5062663 (2025-07 Cumulative Update Preview) Win10 22H2 KB5062649 (2025-07 Cumulative Update Preview) Win10 1809 KB5063877 (2025-08 Cumulative Update) Server 2019 KB5063877 (2025-08 Cumulative Update) Server 2022 KB5063880 (2025-08 Cumulative Update) Server 2025 KB5063878 (2025-08 Cumulative Update) As always, organizations should verify that their update policies align with the new servicing approach before the broader rollout reaches all supported Windows platforms later this year. In case of major problems, the EDR update can be rolled back to the inbox version stored in %ProgramFiles%\\Windows Defender Advanced Threat Protection (ATP) using: MpCmdRun.exe -RevertMde -Product Edr -ToVersion Inbox For those who have access to the Microsoft 365 Admin Center portal, you can view the message here under ID MC1381119.
    • My problem with these smart scopes is that IMO they're not really an entrance into astronomy, they're an entrance to looking at pretty(ish) pictures that you take by essentially pressing a button and letting the scope do the work. I still maintain that getting some binoculars or a solid dedicated telescope (which doesn't have to mean expensive) and actually spending time learning the night sky and using a telescope is a much better way to actually learn. But, granted, the learning curve is a bit steeper (as it tends to be).
    • I never played Crazy Taxi before, but this looks like a fun game!
    • The perception of Microsoft Edge is unfortunate as it's a world class browser. I'm not exaggerating when I say it's the best browser I've ever used with its feature set, speed, reliability and advanced security. Running the extension Ublock Origin is a must though to deal with advertising and trackers.
