If anyone's still interested, it's a trivial line of JavaScript.

[Select]

javascript:document.title=prompt("Rename Tab", document.title);void 0;

For even quicker access;

assign a keyword to the bookmarklet, for example: keyword = Q.
in Firefox, hit Alt+D (to place the insertion point in the address bar)
hit 'Q' + Enter, and away you go!

What am I doing wrong? When I do as you suggest Firefox opens a new, blank tab and runs the Rename script, i.e. it doesn't rename the current tab as when I run the Bookmarklet "manually".

does your "Rename Tab" bookmarks entry look like this?
