Description

If you open a userscript directly (e.g., http://example.org/script.user.js), instead of opening the userscript via a hyperlink, you sometimes have to click the 'Install!' button twice before the installation dialog actually disappears. If you take a look at the gm_scripts folder after the installation, you'll see a duplicate of the script is made (script.user.js => script-1.user.js). I received no errors from Greasemonkey in Firefox' Error Console.
