You need an add on to do with his. Go to the Add-Ons page and select Extensions. Type Manually Sort Folders into the search box. Select it from the search list and click Install.

Perfect! Thanks.

I have some email accounts that are more important and more used than others. I would like them at the top of my "all folder" list for efficiency. Should be a simple task but can't figure out how to do it. Thanks

The "Manually Sort Folders" selection does not appear now. What is the new link to get to this add-on?

It appears just fine for me when I follow my own instructions.

Here is the link to the page. https://addons.mozilla.org/en-US/thunderbird/addon/manually-sort-folders/?src=search

I tried to download the app, but it won't download, because Thunderbird won't accept an add-on that has not been verified.

Such simple instructions. No idea why people have trouble following them. I just followed my instructions listed above and it installed just fine.
