Love it! So Worth Installing Rated 5 out of 5 stars
Great job on creating an add-on that helps with productivity by saving a lot of time from having to sift through all emails or by having to change the sorting view, then select all etc.
I sort my messages by date and don't like having to switch views just to clean things up.
I was using it to just file emails into folders, but it occurred to me that I could use it to select all and delete the large accumulation of frequently delivered emails from social networks, mailing lists etc, and delete them quickly.
Thank you for the time and work that you put into developing this.
I do hope that you'll be updating this for Thunderbird 3.
