Rated 5 out of 5 stars
I have used this add-on for more years than I can remember. Every time Thunderbird breaks it, I realize, again, how much I rely on it on a hourly basis. It is by far the quickest way I know of to quickly separate the "wheat from the chaff" - to be able to focus on those emails that will be paid attention to from those that don't need any attention. I add my voice to those asking Adam to update it as quickly as his schedule allows.This user has 2 previous reviews of this add-on.
