Hi. This is not nvda at all. When I test on production release which I have on another machine, it is fine. It is reading lots of extra text about imap syncing which happens a lot.
Also, if you don't turn off the status bar, it will tell you when you move a message to trash, and a bunch of other info which really adds up quickly. It is certainly a thunderbird change.
Also, some features of the mozilla apps enhancement no longer work such as the ability to sort columns in folders.
Brian.
