I have only tested Mac OS X 10.6 and 10.7. STR: 1. Select menu item: Tools > Web Developer > Web Console 2. Close Web Console using X button or OPTION+CMD+K keyboard shortcut 3. Look at menu item again: Tools > Web Developer > Web Console AR: The Web Console menu item will be checked, even though the Web Console is no longer open. ER: The Web Console menu item should not be checked when the Web Console is not open. I believe this bug is a regression in Nightly 2012-04-28. The pushlog regression window between builds 04-27 and 04-28 is: https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=450d8cd16316&tochange=b5c0d6abf69b 4-20 = PASS 4-25 = PASS 4-27 = PASS Built from http://hg.mozilla.org/mozilla-central/rev/450d8cd16316 4-28 = FAIL Built from http://hg.mozilla.org/mozilla-central/rev/b5c0d6abf69b 4-29 = FAIL 5-15 = FAIL 5-20 = FAIL 5-24 = FAIL 5-26 = FAIL 5-28 = FAIL
