Also when this error is presented after clicking Stop script on the error from comment 0 the attached message is shown in the browser console.

Dão, can you take a look? Are we getting resize events from the wrong code, or is the popuphidden/popupshown code added in https://phabricator.services.mozilla.com/D46624#C1630552NL4892 perhaps firing for the autocomplete popup from the search widget and interfering with things that way, or something?
