Excellent Rated 5 out of 5 stars
I find this to be a highly useful extension. I added it to both Thunderbird and Firefox. Although many years of education, I still find many many many words I don't know the meaning of... I think I missed that course! Thanks very much for this great extension! I've found it works quite well both in Thunderbird and Firefox!This review is for a previous version of the add-on (2.0.2).
