Hello! Here is the situation. I'm constantly getting the unresponsive script whenever I'm on Youtube. At first, it didn't happen and then it started irregularly and then now it is happening constantly. I've always enjoyed Mozilla and so I immediately tried all the recommendations from Mozilla troubleshooting. Nothing worked. Finally, I decided to reset my browser thinking that would do it. It seemed like it helped, but then the error message appeared again. This time a new factor entered the situation leading me to wonder if it has been the problem from the beginning: my Xbox 360. I've paired my devices; my laptop MacBook Pro and my Xbox. I realized the only time the unresponsive script message appears is when I'm playing something from my computer to my TV through the Xbox. Although this hasn't always been the case, it seems to be and more often. Is there a solution? Am I correct to isolate the problem? Can you help? The responsive script listed is chrome://browser/content/places/browserPlaceViews.js:1077 and chrome://browser/content/places/browserPlaceViews.js:18356 Thank you.
