Bookmarks: in Thunderbird 115 Add current item not working

[RealRaven2000]

Regression in Tb 115 when clicking on the bookmarks menu and selecting "Add current item"

we are getting some error messages.

In 3pane mode:
Not supported: bookmarking mail3PaneTab tab!

In a single message tab:
Not supported: bookmarking messageTab tab!

there is also a message on dragging a message to the button, which works as a fallback solution:

this is partly caused by new tab mode names in Tb 115. For single messages, the mode is named "mailMessageTab" and not "message" anymore. This created a number of issues in the latest version of QuickFolders making functions like QF Categories not work in single message tabs.
