Rated 5 out of 5 stars
A long-time and hopeful user of Xpunge and MultiXpunge with multiple gmail, yahoo, and corporate email accounts on Thunderbird, I have found this add-on to be essential, but problematic emptying and compacting my yahoo Trash and Spam bins. For both my yahoo accounts, I invariably have to manually empty and compact these folders, and since it doesn't work, often get TB message to manually compact. With the amount of trash and junk emails exponentially rising, this addon's capabilities are a must.
This problem happens with both my Yahoo accounts, which I've removed and re-added on multiple occasions. It doesn't happen with my gmail accounts.
