Play YouTube Videos Oldest-to-Newest

---------------------------------------------------------------------------------------------------- ✦ Notice: [Fixed] May 16, 2026: We have released a fix (v1.1.3) for issues that had been occurring since around May 2026, likely due to changes to YouTube’s UI. These included cases where the “Play Oldest First” button did not appear, as well as cases where clicking the button displayed a message indicating that the oldest video could not be found, preventing the extension from working properly. If the issue persists, please contact us using the contact information listed in the details section. ---------------------------------------------------------------------------------------------------- 1.
