Looks like a regression from our WE stuff, bug 1455471.

Richard, do you see this in a Daily?

You can see this on automation as well, for example here:
Yes, I see this too. Interestingly the first time it shows no error but opens the tab in background. And from the second time it shows the error ...and opens the tab also in background.

Attached patch 1472494-newtab-error-1.diff (obsolete) — Splinter Review
I mentioned this in bug 1455471 comment 16. Now I understand what the cause is. A "new" tab of some times isn't new at all, it's the same tab reused for the new purpose. So adding the listener a second time raises an exception. I think we can safely catch the exception and move on.

Review of attachment 8989098 [details] [diff] [review]:

Hmm, is there no better way to do this? Can't we track whether we've already attached a listener? For example, in MsgComposeCommands.js we have a dictionaryRemovalObserver with an 'isAdded' property. Could something similar be done here? I haven't looked at all.

This should be Cr., no? We've been replacing with Ci., Cu. and Cr. all over.

> Better?
Well, you tell me. I think it's always better to consciously control than to deal with the fallout of random events.

Does with this patch the tab open again in front when opening it (see comment 3)? Or am I the only there this happens?

don't attach progress listener more than once. r=jorgk

Umm, "Open Message in New Tab" always seems to open in a non-active tab. Am I missing something or are you?
Target Milestone: --- → Thunderbird 63.0
Tested now also on TB 52 as reference. Yes double click opens in front and through menu in background.
