In my experience 99% of such bugs are caused by prefs and I have found bisecting my user_prefs.js file a very effective way of finding the culprit. The sucky part of this solution is that bisecting the user_prefs.js file is a manual process and we overwrite the file at shutdown so you need to be careful with that and keep a backup of the file around, etc. HTH, Ehsan _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
