Review for Remove Duplicate Messages by John Rose
Rated 4 out of 5 stars
When one selects the top folder if using gmail (i.e. the folder containing all the other message folders), then the addon shows duplicates for all/many messages. This is because all/many messages have duplicates on Gmail's server (e.g. in the All Mail or Important folders). It would be good if there was a checkbox to ignore the Gmail (server) folder. This could be in the General Settings tab for Preferences. Also, it would be helpful if the attributes columns for the messages could contain an indicator showing whether an attachment is present on a message. This is because of a fault in Thunderbird for Gmail (and possibly other imap email) which results in there being 2 copies of a message when a message has its attachments detached: one copy is of the original message still containing attachment(s) and the other copy contains the message without attachment(s).
