User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:21.0) Gecko/20130114 Firefox/21.0 Build ID: 20130114031033 Steps to reproduce: Tried to take a screenshot using the developer toolbar using "screenshot test false false 0 true" and "screenshot test 0 0 0 1" and various other combinations. Actual results: The command would not accept any arguments other than the filename whereas the "help screenshot" opens a popup showing that the syntax is screenshot [filename] [clipboard] [chrome] [delay] [fullpage] [selector]. As soon as I type "screenshot test a" or "screenshot test 0" or "screenshot test false" a popup opens saying "Available options - Too many arguments" Expected results: The command should accept the arguments listed in the help for that command.

Thanks for the report. The issue here is that we changed the way the screenshot command works to be a bit more unixy about the way it handles options, so options are now prefixed with --. See the details on bug 799769 for more. Thanks.
