Most useful extension I use Rated 5 out of 5 stars
Without a doubt this is the one extension I hold off upgrading for. It is, by far, the most useful add-on I use. Once you get accustomed to using it, it is very hard to be without it. I agree with several others; IT SHOULD be an integral part of Firefox. Please keep it updated. Thanks.This user has 2 previous reviews of this add-on.
