Target: Flash Ads

Land in Nightly on Desktop for all platforms, *preff'd off*

Target Audience

Flash and web developers who want to test their content with Shumway and a general audience of folks who are interested in a Flash Player Alternative and want to provide feedback

Landing Criteria

• [ON TRACK]Playback Flash Ads from white listed sites on all Desktop Platforms
• [AT RISK] Create developer and user friendly look and feel bug 905705 - WebDev for Areweflashyet.com
• [ON TRACK] Criteria includes:
  • Confidence that we render enough content
  • Confidence that if we are unable to render content, we fail gracefully and give the user the ability to provide feedback (akin to submitting a crash log?)
  • Acceptable CPU usage
  • Acceptable Memory Usage

Now that Shumway has landed, how do I enable it?

• Easy. on Fx27 Nightly, just go to about:config and search for shumway.disabled. Flip that pref to 'false' and you should be all set
• There are other prefs to explore which you can read more about, here: https://github.com/mozilla/shumway/wiki/Debugging-and-Configuring-Shumway#using-the-extension

What about the Summit Demo?

• You can check it out, here: http://areweflashyet.com/summit2013/candy.html

M2 (Due:TBD)

Target: One Instance of Shumway

• [PLANNED] One instance of Shumway and preferably in a worker (off the main thread may work, too)
• [ON TRACK] Land telemetry probes bug 900566
• [PLANNED] Make Firefox for Android more testable
• [PLANNED] Incremental Progress on UX Implementation bug 905679, bug 905705
• [PLANNED] Enable some games

Product Roadmap & User Stories [In Progess]

M1 [ON TRACK]

• As a Metro Firefox user, I experience rich ads so that I don't have to see a bunch of empty boxes as I surf the Web without Adobe Flash player.
• As a Firefox user, I have a more stable browsing experience because Firefox natively renders Flash ads, increasing my user satisfaction, usage, and likelihood to recommend.
• As a Firefox user, I have a more responsive browsing experience because Flash ads in background tabs are throttled, increasing my user satisfaction, usage, and likelihood to recommend.
• As a Firefox user, I can opt in to Firefox native Flash support so that I can help Mozilla test the feature.
• As a Firefox user, I have a mechanism to revert to the Adobe Flash player for specific content blocks, so I am not broken in cases where Firefox's native rendering is insufficient.
