Comment (by learningcrumb):

 The problem described in 24504 goes away if I bundle the extension as an

 So it's clear it only happens when the extension is a directory of loose
 files rather than an xpi file.

 Therefore, I agree that 24504 is a duplicate of this ticket.

 I guess I could have saved myself some time building that test case if I'd
 looked more carefully at existing tickets... but mostly I'm just glad to
 have a workaround I can use immediately.

 Thanks for spotting the link gk!

 Incidentally, while testing just now I did see some strange behaviour with
 pings from an embedded WebExt only appearing in the Browser Console if the
 console was open when the button was hit, disappearing again when the
 console was closed and reopened, while messages from the outer extension
 itself behaved normally. It may not be important. If I have time I will
 look into it and open a separate ticket if necessary. Just mentioning it
 in case I don't get around to it and someone else feels like
 investigating. This was while using the test extension from 24504 bundled
 as an xpi.
