Close Remember The Milk Tab Firefox
When logging in to Remember The Milk for GMail (at least in Firefox with TabMix Plus) a rather annoying empty tab is left open, with no content. This page actually has a JavaScript close instruction, but by default a JavaScript is not allowed to close windows that it didn't open.This can be overcome by entering about:config into the Firefox address bar, and double clicking the dom.allow_scripts_to_close_windows to set it to 'true'. A warning is in order: now JavaScripts can close windows (tabs) that they didn't open (I haven't had any problems with this however).
