🐞 Automatic Transcript Issue with YouTube History and Watch Later Sections

[Kilk1]

Concise Description

Hello,

I’m using Firefox and have noticed that the automatic transcript feature isn’t working as expected when accessing videos from YouTube’s History (https://www.youtube.com/feed/history) or Watch Later (https://www.youtube.com/playlist?list=WL) sections. Despite enabling the feature, I need to refresh the video page for the transcript to appear after selecting a video.

I’d appreciate any assistance in resolving this issue. Thank you!

'Steps to reproduce' - Which of our features is required for the bug to happen?

Steps to reproduce: Open Firefox and navigate to YouTube’s History (https://www.youtube.com/feed/history) or Watch Later (https://www.youtube.com/playlist?list=WL) sections. Select a video, and the automatic transcript does not appear, despite having the feature enabled in the "Improve YouTube!" extension. A manual page refresh is required for the transcript to load. The feature involved is the “Automatic Transcript” functionality.

Since when?

I’m not certain exactly when this issue started, but I noticed it recently. For all I know, it’s always happened when going to History or Watch Later.

Does the bug still happen when you log out of YouTube?

Yes

..No? Then please paste your yt.config_.EXPERIMENT_FLAGS. Twice (With the error & Without)

Are any errors or related log-messages shown in the Browser-Console? (F12)

Yes, there are several messages shown in the Browser Console, including Content-Security-Policy warnings about blocked inline scripts, Cross-Origin Request Blocked errors for resources from Google Ads and Google Play (CORS request failures), and a TypeError: a.default.detectStore(...) is undefined in h1-check.js. There are also multiple deprecation warnings, such as MouseEvent.mozPressure and MouseEvent.mozInputSource, along with cookie warnings and a WEBGL_debug_renderer_info deprecation warning in Firefox. These errors appear on both the Watch Later page and the video pages accessed from Watch Later.

Tested as the only active extension? (incognito mode or another browser users):

No

Expected preferred behavior:

The expected preferred behavior is that when I click on a video from YouTube’s History or Watch Later sections, the automatic transcript feature should immediately load without requiring a manual refresh of the page. The transcript should be displayed automatically as soon as the video starts, as it does when accessing videos directly outside of these sections. This would ensure a seamless experience without needing additional steps to trigger the transcript feature.
