Connectivity: wifi device: Android 38.0a1 (2015-01-20) steps to reproduce: 1. Load https://marketplace-dev.allizom.org on your latest nightly 2. User is logged in 3. Search for :paid apps 4. Click the buy button for a paid app (I used Compound Interest) expected behavior: webpay screen for Enter PIN loads actual behavior: stuck at the loading screen (chrome://browser/content/payment.xhtml) 01-20 11:24:21.965 W/GeckoConsole( 4695): [JavaScript Error: "NS_ERROR_FACTORY_NOT_REGISTERED: " {file: "https://marketplace-dev.mozflare.net/mozpay/spa/js/main.min.js?bust=fa9c15f39724a9f8ede7f2b66097197e4da8a750" line: 62}]

Suspecting that I asked you to test Android too quickly and bug 1097928 hasn't landed yet. Sorry about that.

I can still repro this with latest nightly: I/GeckoConsole(20618): [lib][tracking] [tracking] Setting up GA tracking I/GeckoConsole(20618): [lib][tracking] Tracking initialized I/GeckoConsole(20618): [views][app] I AM SPARTACUS!

FFAndroid version is 38.0a1 (2015-02-04)

Ok so after unravelling the file and proxying an un-minned version of our code the line that we're getting this error on is: https://github.com/mozilla/spartacus/blob/master/public/js/lib/utils.js#L134 The suspect is navigator.mozId. Poking at just that is enough to cause that error. Here's a testcase: http://jsbin.com/juxasu/ Which shows the following in adb. W/GeckoConsole( 8958): [JavaScript Error: "NS_ERROR_FACTORY_NOT_REGISTERED: " {file: "http://jsbin.com/juxasu" line: 19}]

I've filed a platform bug here: bug 1129650 I'll look at wrapping this in a try/catch to see if we can workaround the issue so we can move forward.

Here's a workaround https://github.com/mozilla/spartacus/pull/202

https://github.com/mozilla/spartacus/commit/143653593621982a53b51cfb3e2d59b0e61a2e7e This uncovers other errors I'll file bugs for those separately.
