Hello
I have the same issue than :
https://addons.thunderbird.net/fr/thunderbird/addon/unified-folders-debugging/reviews/1172873/
Or this
https://www.reddit.com/r/Thunderbird/comments/16x867e/comment/k34pyks/?utm_source=share&utm_medium=web2x&context=3
....
When I go into Menu > Affichage > Folders/Dossiers > Unified_folders Thunderbird check it... ok, cool, but directly after, it uncheck it... frustrating me !
I use it to centralise my all workflow so unified was a big thing for me.

I already try to reset Thunderbird with Trooblshoot and new empty profile...

My debug error output when I click > Unified_folders :Uncaught TypeError: about3Pane is null_onFoldersViewShow chrome://messenger/content/panelUI.js:496onpopupshowing chrome://messenger/content/messenger.xhtml:1panelUI.js:496:18_onFoldersViewShow chrome://messenger/content/panelUI.js:496onpopupshowing chrome://messenger/content/messenger.xhtml:1
--> same here : https://www.reddit.com/r/Thunderbird/comments/16x867e/unified_folder_error_11530catalina/
Thanks
