STR: 1) Tour page does: Mozilla.UITour.observe((...rest) => console.log("observed", rest)) 2) User opens same tour page in a new tab 3) User closes the newly opened tour page and gets switched back to #1 4) Firefox does UITour.notify(…) Expected results: The original tab should still receive Loop events. Actual results: The original tab no longer receives Loop events. Please note that using Page Visibility API to re-register the event listener does not work in this instance.

Alex, can you see if the quote in comment 1 is still a problem. If not, can you dupe this to bug 1110602?
Hi Matt - just tested and yes this seems to be fixed now. Thanks again!
