Updated Firefox browser for desktop on Mac to 158.0 on 10/15/26
On 10/14/26 using previous Firefox version 157.0 on Amazon.com Prime Video section, pages would load properly and videos could be played properly.
10/15/26 using updated version on Amazon.com Prime Video section, page would initially load properly only to later freeze. Videos could not be played. And freezing could not be corrected unless closing the tab on the browser.
10/15/26 using Safari browser on Amazon.com Prime video section, pages loaded properly and videos played properly.
Clearing cache and site data on updated version of Firefox did not have any effect. Pages continued to freeze and videos unplayable when starting over and navigating to the relevant pages.
Steps to reproduce:
go to amazon.com login to account go to prime video page
expected results video selection appears and user can select and play videos
actual result video selection appear but freezes after a second or two,. videos cannot be played
Repro rate 5/5
