Text not being replaced, but no errors in console about format HOT 2 CLOSED

The issue in these cases appears to be that the correct frame is never identified, becausemessage.href is undefined

messaage.href is set according to information passed from the browser itself to an event listener. (queryURL). I need to figure out if message.href is never being set, because queryURL for some reason isn't being called or if it is being explicitly set to undefined perhaps because the message was sent too early (DOM hasn't fully loaded).

The former seems more likely at this point...

There appears to be two causes to this issue. The first is that the tab change listener wasn't creating an href key in the object it passed to queryURL. This is what was causing hrefTop to be undefined sometimes. The fix has been implemented and will be committed today.

However there is a second cause to the problem. Sometimes, (especially prevalent in youtube) the url can change, but a new page is not actually loaded. Because hrefTop gets set when the top frame is loaded, the value of hrefTop becomes outdated, so the correct frame never gets found. You can switch tabs to fix this (now that tab switching works) I am opening a separate issue for this.
