Review for ImportExportTools NG by YEC
Rated 2 out of 5 stars
Recently, with this (useful) extension, the automatic retrieval of emails AT THE FIRST START of Thunderbird no longer works. Only deactivation makes the first retrieval problem-free again.
Since it's been happening recently, could it be due to an update to Thunderbird? But without this extension everything works. So it remains disabled.
