JS (naveed)

<Read Only>

No update this week

Layout (jet/dbaron)

Media (mreavy)

  • The former Talkilla team now reports to mreavy, and the project has been renamed "Loop" (codename, NOT a product name)
  • Landed final support for B2G getUserMedia video (rotation (bug 970183) and front/back camera support (bug 898949)). So gUM video is scheduled to ship in v1.4. If you have problems with gUM video on B2G, please file bugs and cc mreavy.
  • If you're using a Mac with WebRTC in speakerphone mode and it echoes badly, try adding this pref: media.peerconnection.capture_delay: 50 (bug 974537)

No update this week

Seceng (mmc)

<Read Only>

  • Support for OCSP (bug 915931) and certificate error overrides (bug 975122) were added to insanity::pkix, the new certificate verification library replacing NSS's certificate verification. insanity::pkix for TLS is still pref'd-off (security.use_insanity_verification=false). It is expected to be enabled soon, after EV support (bug 921895) and OCSP caching (bug 915932) are added, and after more testing is done. If you don't care about your own HTTPS security and you play with this, please report any issues, particularly compatibility issues, in the "Core :: Security: PSM" component ASAP.
  • Signed packaged app installation, based on insanity::pkix, was uplifted to Aurora 29 (bug 896620). While it is unclear which release packaged app installation will officially get enabled for, with this you can already play Cut-the-Rope in Firefox 29 Aurora and Firefox 30 Nightly (tested on Windows):
    • Go to https://marketplace.firefox.com/app/cut-the-rope?src=search
    • Using Firefox Developer Tools, remove the disabled="" attribute and the "incompatible" class from the app install button (labeled "free"). This will enable the button.
    • Click the button.
    • You will be prompted to install the app. Approve the install.
    • You will get a system tray notification. Click "run the app" in the notification.
    • The app will start up full screen. Play the game for a while.
    • Exit the game.
    • "Show Desktop."
    • Observe that the "Cut the Rope" application shortcut is on the desktop.
    • Double-click the shortcut to start the game again.
    • Play the game some more.
    • Occasionally look up so it looks like you're paying attention to the rest of the updates in this meeting.
  • Application Reputation: Landed bug 964465 support for whitelisting based on certificate information
