Rated 5 out of 5 stars
QuickFolders is one of my favourite add-ons. I use it to manage different email accounts in an efficient way and just to quickly switch between my most used folders. In fact this add-on is already useful when you just have one email account!
The use and options of QuickFolders are straightforward and some clear instructions are available.
Since version 2.7 is not compatible with Thunderbird 5.0 an update would be much appreciated and worth another donation... keep up the good work!
