Superb + extensible Rated 5 out of 5 stars
I discovered this recently and have come to rely on it at least a few times a week - beyond the ads it's blocking for me. Whenever I sign up on a site where I might suspect them of spamming me, I use a disposable email now. I find I've actually done this a few times this week. Surprisingly easy. Caveat: sometimes the email window does not come up for me as expected. I suppose this is because the software is new?This review is for a previous version of the add-on (3.1.1037.1-signed).
