Rated 5 out of 5 stars

I have been using this add-on for many years, and consider it a huge benefit of using Thunderbird as opposed to Outlook, Gmail, etc. Great great tool. I would give it ten stars if I could! I recently updated to a recent version (91) of Thunderbird and found that QFM worked perfectly--and I would have gone back to old Thunderbird if it didn't. Thank you Philipp for this great piece of work, and for updating it as needed.
