Review for Remove Duplicate Messages by brucemc
Rated 5 out of 5 stars
After 15 years of accumulation and imports from Outlook Express to Eudora to Thunderbird, I only had roughly 15,000 duplicates. Is that good?
THis extension did an excellent job of sorting, offering options, and blowing them away. It gave me total control over each step of the process and did the job. The only things I did thereafter were to empty and compress the trash folder, but this is a good safety net if someone has second thoughts after initiating the delete for some reason. About the only item that might use clarification is naming the darned download file to what the extension is, as presently it is something rather cryptic.
