Why wouldn't everyone use this? Rated 5 out of 5 stars
If you use Thunderbird and Google products like calendar, voice and docs like I do, you will be amazed by what this extension does to improve productivity. Makes me mad that I did not install it or know about it earlier. Amazing - Best Extension Ever! ( I never do reviews but had to let others know about this add-on )This review is for a previous version of the add-on (2.3.0).
