Rated 5 out of 5 stars

Was not available for a while due to Thunderbird upgrades, but now since version 3.3. works again flawlessly. This is *very* useful and speeds up navigating to a specific folder, especially when you have a lot of folders and subfolders: place focus on tree, when start typing, jumps to next visible folder that satisfies the letters typed thus far. does not open or look in subfolders that are not visible or closed. Thank you Andrew for making this great tool!

This review is for a previous version of the add-on (3.3).
