While working on bug 940164,
I find that navigator.mozApps are undefined until several try.
### Codes

      for (var api in this.REGISTRY) {
        this.debug('Detecting API: ' + api + ' and corresponding module: ' + this.REGISTRY[api]);
        if (navigator[api]) {
          this.startAPIHandler(api, this.REGISTRY[api]);
        } else {
          this.debug('API: ' + api + ' not found..retry!');
          var self = this;
          var interval = window.setInterval(function() {
            if (navigator[api]) {
              window.clearInterval(interval);
              self.debug(api + ' found!!!');
            } else {
              self.debug(api + ' not ready yet..')
            }
          }, 1000);
        }
      }

### Logging
"[SystemApp][1.141] Detecting API: mozApps and corresponding module: ApplicationsMediator" app.js:16
"[SystemApp][1.141] API: mozApps not found..retry!" app.js:16
"[SystemApp][2.750] mozApps not ready yet.." app.js:16
"[SystemApp][3.355] mozApps found!!!"

Fabrice, are you aware of this? Is it intentional or something we cannot resolve?

I had that problem in bug 1035867, which was a regression from bug 903291.  We ended up fixing it by removing some unnecessary code, although it never made sense for that code to cause the problem, and I continue to suspect a regression from bug 903291.

Yes, that should not happen. Do you have a logcat?

Not sure what kind of log you need but I attach the full logcat.
From the log you could see we have navigator.mozApps at 5nd retry.

This doesn't happen anymore when I updated my gecko. Closing. Sorry for disturbing.
