Steps to reproduce:

- Launch Thunderbird version 91.4.1  or 91.6.1 under Windows 7 Home.
- Open address book.
- File -> New -> Address Book ; name it Book-A.
- File -> New -> Address Book ; name it Book-B.
- In Book-B, File -> New -> Mailing List ; name it Book-B-List1.
- Add contacts to Book-B-List1.
- Configure the address-book-window so all address books are visible in the left pane and Book-B is visible in right pane (with all of its contacts and the sole group Book-B-List1).
- Drag Book-B-List1 from the right pane to over Book-A in the left pane.
RESULT:
The mouse icon/pointer is ALWAYS/EVERYWHERE the circle-with-slash-at-45-degrees -- even when hovering over the intended destination Book-A. So, cannot copy-move group/list to the desired address book.



Actual results:

ENVIRONMENT:
Windows 7 Home, Thunderbird versions 91.4.1 brand-new installation, then updated to 91.6.1; importing an address book from Thunderbird version 52.
CONTEXT:
Had been using Thunderbird version 52 for years. Had created several groups/lists of contacts in default "personal addressbook". As part of migration, (a) grabbed abook.mab and history.mab from profile; (b) exported address books into all availble formats {csv,tsv/tab,vcf,ldif}. On same machine and OS, upgraded to version 91.4.1. The "upgrade" was NOT by upgrading (overwriting) the existing thunderbird version 52; "upgrade" by installing completely separate "brand new" thunderbird (by specifying a different install directory under 'Program Files (x86)'). Never using calendar. Used email (of version 91) for two months with default address books as-they-are; no imports or manual edits. Today, while working on these trials with address books, Thunderbird was kept OFFLINE to avoid changing (minimizing) changes to files in profile. Prior to the first change, copied profile in entirety. Upon encountering a problem and before the next trial/attempt, completely restored profile to pre-trial state. INITIAL INDICATION: Imported version 52 address books into version 91.4.1. Result: Thunderbird created a new address book (referred to here as "Book52"); mandatory; I observed thunderbird cannot/does-not import into an existing address book. My version 52 contacts and groups/lists appeared in the Book52. I was able to drag individual contacts from Book52 to default "Personal" book. But was not able to drag a group/list from Book52 to "personal" book. The pointer icon was always/everywhere the circle-with-slash-at-45-degrees -- even when hovering over the intended destination. Updated from Thunderbird version 91.4.1 to 91.6.1. Same behavior. Restore. Tried importing the "mab" file. Same result. Restore. Tried importing the "ldif" file. Same result. Restore. Manually created address books and groups/lists for this bugzilla. Same result. Reporting via bugzilla.



Expected results:

1) With ver 91.4.1 or 91.6.1, there is no way to move-copy a group/list from Address-Book-A to Book-B. Program does allow move-copy an individual contact. A group/list is no different; should be able to move-copy from Book-A to Book-B.
2) BASIS FOR BELIEVING OLD BEHAVIOR IS NOW BROKEN:
https://support.mozilla.org/en-US/questions/1127568, 2016JUN17, Home -> Support Forums -> Thunderbird -> "How can I move/copy a mailing list"
This webpg says 'drag group from right pane onto the address book shown in the left pane' [paraphrase].
So, I believe drag-and-drop had been the way to move-copy a list of contacts from one address book into another book.
