Status: VERIFIED FIXED

(Shield :: General, defect)

Description

[ovidiu boca[:Ovidiu]]

[Affected versions]:

Firefox Nighlty 54.0a1(2017-02-23), Firefox Aurora 53.0a2(2017-02-23)

[Affected platforms]:

Mac OS X 10.10, Ubuntu 16.04, we didn't try on Win


[Steps to reproduce]:

1. Set up my FF profile for testing
2. Run in Browser Console this: 

Cu.import('resource://shield-recipe-client/lib/Storage.jsm');
Storage.clearAllStorage();
Services.prefs.setCharPref("extensions.shield-recipe-client.api_url", "https://normandy-mock.dev.mozaws.net/HeartbeatLongMessages/api/v1");
Cu.import('resource://shield-recipe-client/lib/RecipeRunner.jsm');
RecipeRunner.start();


[Expected result]:

The recipe is executed and you can interact with the browser. 

[Actual result]:

After some time (~10 sec) the browser becomes unresponsive and all the screens flickers and CPU is more than 100%.

Note: I also run the other 2 mock test recipe that contains Heartbeat and this issue doesn't reproduce.
