New Google Toolbar
Since a technically inclined person is more likely to be using the Google Toolbar (particularly the advanced features in this version) (you can program buttons on it), and since a technically inclined person is more likely to be using Firefox, I'm a bit surprised they don't have a Firefox version ready already. If they did, I'd install it. However, as of right now, I'm stuck with an older version of the Toolbar which doesn't do the neat things that the IE version does. I suppose its better than no toolbar at all though.
