I have no programming background so the following may be stupid.
Do you need onpopuphidden/onpopuphidding after onpopupshowing to prevent memory leak? I see examples of these like https://bugzilla.mozilla.org/show_bug.cgi?id=708071 and https://adblockplus.org/forum/viewtopic.php?t=8866.
Please kindly ignore me if this is a really stupid question. :)
