Excellent - but please update for Thunderbird 6! Rated 5 out of 5 stars
The update to TB6 disabled this add-On — and since, at every message I write I notice how much I miss this Add-On., because I use the home and end keys all the time. (Seriously, @Apple: Who on this planet needs to jump to the end of the page more often than to the end of the line!?)
Pleeease update for Thunderbird 6!
