Rated 5 out of 5 stars

I was able to backup about 170,000 attachments in over 55,000 emails thanks to Extract Em and clear out space on my email inbox. I had tried the extension called Attachment Saver and that only backs up 600-700 files in one zip so that didn't work for me. Other addons weren't supported by newer Thunderbird versions. So I'm glad this extension works as advertised even for large operations. The dev was fast to respond and to fix an issue with my use case so I'm thankful for that as well! Thanks for making this extension

This review is for a previous version of the add-on (1.1.1).
