Firefox for Android should support W3C Wake
I recently wrote up a meditation application and uploaded it to the Firefox marketplace: https://marketplace.firefox.com/app/meditation Unfortunately it doesn't work particularly well on Android, because the screen turns off while the timer is counting down and the end "chime" sound never plays. On FirefoxOS, I used the requestWakeLock API to avoid this problem: https://developer.mozilla.org/en-US/docs/Web/API/Navigator.requestWakeLock API ... it would be great if Firefox for Android supported this as well.
This should be trivial. Add the wakelock pref (dom.wakelock.enabled) to the list of things to turn on in apps: http://mxr.mozilla.org/mozilla-central/source/mobile/android/chrome/content/WebappRT.js#27 If you have time/environment to do that, you're in a much better place to test the api than anyone else :)

As long as release the lock when the webpage is left, we should be fine, right? This is the way it works for FirefoxOS.
Hmm... that would be interesting. I don't know enough about the topic to comment. Probably a good dev-platform post to see what people think. The fix should also try and make sure the apk factory is updated to include the wake_lock pref is apps request it: <uses-permission android:name="android.permission.WAKE_LOCK"/>
tracking+ for now, but we can track for a release if we decide to do a webapp API-focused release.

Sounds like fixing this bug would just involve flipping a pref and doing some testing.

I really haven't had the time/inclination to work on it myself, but it would likely make a good first bug for someone who wants to get started. To test that it works, maybe just install my meditation app (https://marketplace.firefox.com/app/meditation/) and do a 5 minute session. Make sure the screen stays on for the duration.
There is now a W3C API for wake lock management: http://w3c.github.io/wake-lock/ It has been added an experimental feature in Chromium: https://codereview.chromium.org/1107333002/
Summary: Firefox for Android should support Navigator.requestWakeLock API → Firefox for Android should support W3C WakeLock API
