Created attachment 8853757 [details] firefox-popup-test.zip User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:52.0) Gecko/20100101 Firefox/52.0 Build ID: 20170329150444 Steps to reproduce: Install the attached WebExtension, enter some texarea and press the shortcut Ctrl+Shift+Space: the popup will not open. Now change the manifest.json so the shortcut is Ctrl+Shift+B, reload the add-on and the new shortcut will work. It seems non-character shortcuts in general don't work here (I also tried Return and Comma). Tested on Ubuntu 16.04. Ctrl+Shift+Space also works in Chrome, so it doesn't seem to be blocked by something else.
