User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/42.0.2311.152 Safari/537.36 Steps to reproduce: Using Firefox for Android 38.0.1 from the Google Play. Cleaned all data before doing these steps and no addons are installed. A1. Go the the Firefox Marketplace A2. Select the Twitter web app A3. Click on "Free" to install it Then tried to download the apk and installing it via adb: B1. Downloaded the apk manually doing curl -v -k https://controller-review.apk.firefox.com/application.apk\?manifestUrl\=https://mobile.twitter.com/cache/twitter.webapp -o twitter.apk B2. Successfully downloaded it so installed it: adb install twitter.apk B3. Successfully installed it and opened it Actual results: A. Got an error installing the app and the following log on logcat D/GeckoWebappManager(28389): error downloading APK: 504 - GATEWAY_TIMEOUTD/GeckoWebappManager(28389): error downloading APK: 504 - GATEWAY_TIMEOUT B. When opening it I only got a blank screen (after getting the loading/splash screen with the Twitter logo) Expected results: A. Twitter web app is installed B. Twitter web app opens the Twitter page.
Also tried on Nightly and it does not work. I believe it is a problem somewhere in the Twitter code, as other web apps are working.
Per bug 1235869, we're going to disable the Android web runtime, so we won't fix this bug in it. (This is part of a bulk resolution of bugs in the Firefox for Android::Web Apps component, from which I attempted to exclude bugs that are not specific to the runtime, but it's possible that I included one accidentally. If so, I'm sorry, and please reopen the bug!)
