It worked fine for about 2 weeks, and now anytime I play something on Prime Video and that video ends and automatically moves to the next episode, it will freeze, and Firefox will say the extension is slowing down browsing and to press the stop button to resume browsing. The entire window will freeze, and you can't even refresh the page and will be forced to close the tab to be able to browse again in Firefox.

Edit: Turned off the skip credits feature just like the Developer recommended and it is back to normal now. Even tested it on multiple other show's on Prime Video just to make sure it wasn't a fluke and it is now functioning perfectly on Prime Video. Updating to 5 stars now from 1 star.
