Where is the ability to install custom GreaseMonkey scripts? I've installed greasemonkey. My dialog box under tools only has GreaseMonkey -> [Enabled, Manage User Scripts..., New User Scripts..., User Script Commands (greyed out)]
The "Manage User Scripts" dialog box is here: http://img182.imageshack.us/img182/5907/screenshotat.png
I'm using GreaseMonkey version 0.8.20090123.1 on Ubuntu Linux 8.04 (Jaunty) with Firefox 3.0.14
UPDATE Ok, the right answer here is to rename the file to a .user.js (literal) extension - which userscripts will do for you - and link to it in a webpage. There is no longer an Install Script dialog or anything of that sort that permits you to browse to a .js file and simply install. (that I know of)
