Despite the extension's page here saying that it works with TB versions 128.0 - 140.0, when I try to install it in my in 140 TB refuses to install it and says:

about:addons

Filter on Folder Button could not be installed because it is not
compatible with Thunderbird 140.0.

Buttons work great, but too bad they're fixed. I can move them, but when I restart TB they go back to their original locations. I presume this is an API limitation. Good to have a filter button again though.

This review is for a previous version of the add-on (1.2.0).
