Thread:Project:Support desk/Wikipedia Toolbar

I'm attempting to get the Wikipedia Toolbar working for Firefox 4. I don't have much experience with this stuff, but I've determined the buttons that are not working are due to the fact that they use some global variables. From different pages that I've read, and directly from Manual:Interface/JavaScript, window._content.document.location = wgServer + wgScript + "?title=" + wgPageName + "&action=edit"; should work, but it doesn't. If I take out the wgServer, wgScript, and wgPageName, it works. This is using Firefox 4 on Windows 7 x64 on the English Wikipedia, which is running MediaWiki 	1.17wmf1 (r86464), PHP 5.2.4-2ubuntu5.12wm1 (apache2handler), and MySQL 5.1.46-facebook-r3489-log. Thanks.
