Which undo shortcut, the one on the context/right-click menu? Seems to work for me.
Yes the one in the context/right-click menu.  Still doesn't work with the latest beta update 64.0b3 (today)
Sorry, using this beta I can't reproduce this. I did this:

Write a new message, type something, right-click, context menu shows, type u for undo. Test disappears, that is, undo works.

Try with add-ons disabled, see help menu.
Tried with add-on disabled. N effect context menu undo still doesn't work
Alice, can you reproduce?

Works for me in compose window.

But, "Undo Delete Message", "Undo Move Message" stops working!

For example:
1. Right click on a message in List View
2. Choose "Delete Message"
  --- deleted as expected
3. Edit > Undo Delete Message
  --- Does Nothing, BUG!

Thanks. Well, it would be bug 1446609. BTW, Ctrl+Z does bring the deleted message back.

Aceman, could you please take a look, preferably in a new bug.

Posted patch 1508210.patchSplinter Review
Yes, the cmd_undo and cmd_redo commands didn't get their oncommand= moved from the removed overlay in bug 1446609 in a similar way that the other commands like cmd_cut did in https://hg.mozilla.org/comm-central/rev/6bea4bcfa60f#l12.126 .

Sorry this is way beyond my ability to make a comment or even observation
No problem, we think we found the cause of the problem and it should be fixed in tomorrow's daily build.
Pushed by mozilla@jorgk.com:
wire up cmd_undo and cmd_redo commands again. r=jorgk
