STR: 1) Copy this string to the clipboard "This should only appear once" 2) Open a new tab to data:text/html,<html contenteditable> 3) Select the white background, and use Cmd-V to paste the string from step 1 into the editable area. ER: A single instance of the string from step 1. AR: The string is pasted twice. I bisected this - this is a regression from bug 429824.
Looking into it. Thanks for reporting!

Looks like this is e10s-only.
Summary: Pasting using Cmd-V results in two consecutive pastes → [e10s] Pasting using Cmd-V results in two consecutive pastes
There is a difference between e10s and non-e10s deep within PresShell::HandleEvent here, which causes mTextInputHandler->HandleKeyDownEvent(theEvent) to report that the event hasn't been handled when in fact it has. Even though I'm making progress I don't expect to have this fixed by EOD today. I've backed out bug 429824 since pasting via cmd+v is pretty fundamental functionality.  https://dxr.mozilla.org/mozilla-central/rev/d92fd6b6d6bfc5b566222ae2957e55772d60151a/widget/cocoa/nsChildView.mm#5474
