Rated 5 out of 5 stars
I'm a pretty heavy user of gmail for personal email, and have just switched from outlook to thunderbird for work email - mainly because of outlooks terrible support for threaded conversations. Once in thunderbird I kept 'losing' new messages to old conversations as they'd appear miles down the page, sometimes weeks back. This extension makes it work much better - i.e. much more like the perfection that is gmail. Thank you!This review is for a previous version of the add-on (0.6).
