From bug 1361140 with Browser Console open: - _findActivityObject dominates the profile: https://perfht.ml/2p2cjx7 45% / 1800ms of CPU spent in it. Looking at the code (http://searchfox.org/mozilla-central/rev/3dc6ceb42746ab40f1441e1e659ffb8f62ae78e3/devtools/shared/webconsole/network-monitor.js#1180) shows this is an inefficient loop that should be replaced with a map.
