I've managed to reproduce this issue on the latest Aurora(44.0a2) and on the reporter specified version of Aurora(42.0a2). User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.11; rv:42.0) Gecko/20100101 Firefox/42.0 Build ID: 20150818004007 User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.11; rv:44.0) Gecko/20100101 Firefox/44.0 Build ID: 20151202004004 This bug is not reproducible on the latest release(42.0) nor the latest Nightly(45.0a1). It seams that this issue is only reproducing on Aurora builds. Considering this, I will mark this bug as new and I will assign the appropriate component.
