Enumerating window.navigator on FxOS 1.1 throws a security error (bug 894335). Cordova does exactly that while initializing. If possible, we should identify a workaround for this. Potentially, this could work like this: 1) phonegap initializes and hits the bug, throwing a security error 2) we catch the error, and flip a flag. We connect the APIs to a separate object (window.cordova?) rather than the navigator object instead. 3) developer checks for the flag and if it's present, they talk to the window.cordova object as opposed to window.navigator. That's just one option how it could work.

The first attempt is to try/catch on each key. This fails on 'mozTime' and is transparent for other browsers - https://github.com/zalun/cordova-firefoxos-take-one/blob/232be947289667448ec5c5c54f1611ff247dc4df/framework/cordova-2.6.0.js#L6052

I have finished this. The firefoxos platform in cordova-js now has its own init.js file which overrides the main one, and it adds the try/catch which makes it work. All new projects will get this fix now: https://github.com/jlongster/cordova-js/blob/master/lib/firefoxos/init.js
