I think I fixed the installation problem of this add-on Manually Sort Folders for Thunderbird versions 103 and beyond!!

I am hosting the file in Google Drive. It is in zip format (same as xpi).

To test it, download the zip file then choose "Install Add-ons from file" in the Extension page of Thunderbird! Remember to remove the old version first. I updated the Changelog in the zip package describing what I did.

BTW, I found the following message interesting. It tried to sort the folder tree using userChrome.css.

This one does NOT replace FolderPane Tools (https://addons.mozilla.org/en-US/thunderbird/addon/258), as this one does NOT sort newsgroup (and mail) accounts. It only sorts things inside an account. It's still a useful tool.

Đánh giá này là cho một phiên bản trước của tiện ích (0.4.1). 

Actually, event though it might not replace FolderPane tools completely (which wasn't the goal of this add-on anyway), it DOES sort accounts. Look at the sentence in bold in the add-on description, and look at the first tab of the "Manually sort folders" dialog :).
