User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:21.0) Gecko/20100101 Firefox/21.0 (Beta/Release) Build ID: 20130511120803 Steps to reproduce: This bug is in both Mobile and Desktop versions: 1. Go to about:config 2. Change "browser.urlbar.filter.javascript" to false. 3. Type "javascript:alert('hi')" in the URL address bar. Actual results: Nothing. Expected results: An alert saying "hi" should pop up. This is the only way to debug/fix misbehaving sites, since there's no console or working Firebug/Greasemonkey extension on mobile. I would like it to turn off the annoying bar in an autoplaying Google Presentation, since it covers up my slides!

Yes. But unlike the desktop version, there's no alternate at all.

Sorry, accidentally closed.
