Greasemonkey get names of all open tabs

Question

My ultimate goal is to have an autocompleting list that displays all open tabs (in Firefox), which I can reduce to the tab I want to switch to next.

I can do the completion / combobox etc, but I don't know how to get the list of all names (and favicons wold be a huge bonus). Would be grateful for any pointers.

Answer 1

Doesn't GreaseMonkey run in the context of a single web page? I don't think it can access the other tabs.

If you make a normal extension, you can call window.getBrowser().browsers as is described here:

Aside from learning a little XUL, your extension might be easy to port.
