Excellent! Rated 5 out of 5 stars

You have people that offer buttons that they say mark all emails read, but only mark the emails in that folder read. This addon factually marks the mails in the folder ánd its subfolders read. This is added in the rightclick menu, right under the 'Mark Folder Read'. Very well done! (Thunderbird v45.0)

Brilliant, thanks so much for making this work and acting as a replacement to the original application.
