[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.
