The return key that should start Firefox with the chosen profile now instead confirms its deletion. On my Finnish keyboards the delete and return keys are quite near each other: yesterday I once deleted my profile (luckily not its files) and today I almost did it a second time. Reproducible: Always Steps to Reproduce: 1. firefox -no-remote -P 2. <Delete> 3. <Return> Actual Results: The default profile is deleted. Expected Results: The delete key should be ignored, or if a deletion shortkey is needed, maybe add a shift or other modifier key. Alternatively the confirmation dialog could have Cancel selected as its default action. I cannot reproduce Bug 541615 (Pressing delete in profile does not ask for confirmation of profile deletion).
