[Versions:] -tested on MacOSX10.10 and Ubuntu 16.04 -Reproducible on Nightly54 20170223110219 -Not Reproducible on Aurora53 20170223084136 [Description:] Running any recipe from normandy-admin or mock server will return unknown errors in browser console. (see http://imgur.com/a/v8gLj). [Steps:] 1. Connect to VPN. 2. Obtain a copy of Firefox with the SHIELD recipe client system add-on installed. (at the current time, nightly and aurora have the system add-on) 3. Set the extensions.shield-recipe-client.dev_mode preference to true to run recipes immediately on startup. 4. Set the extensions.shield-recipe-client.logging.level preference to 0 to enable more logging. 5. Set the security.content.signature.root_hash preference to DB:74:CE:58:E4:F9:D0:9E:E0:42:36:BE:6C:C5:C4:F6:6A:E7:74:7D:C0:21:42:7A:03:BC:2F:57:0C:8B:9B:90. 6. Restart Browser. (assuming there is at least 1 recipe to be executed) and open Browser console. ( or use a mock recipe from https://normandy-mock.dev.mozaws.net/) [Actual Result:] The normal shield console execution messages are displayed after which it starts pouring with unknown error messages as shown here: http://imgur.com/a/v8gLj (-after 10-15 minutes it doesn't seem to stop ) [Expected Result:] No console errors. [Note]: We also have some performance related issues that we think it might be related to this bug, since we haven't noticed them in prior tests, so for this reason, I'm going temporarily set the severity to blocker.
Thank you Mark. Further testing on this, I can actually confirm now that this is not related to Shield System Addon. Therefore marking it as a dupe after bug 1341996.
