Release notes for 2.38.2

New
- Setting (advanced): "Remove black & colored bars > Detection: ignored elements"
- Support for embedded YouTube videos

Changes:
- 2 default hotkeys has changed to support rotation via keyboard keys in VR videos: A -> G & S -> H

Improvements
- Styled the new YouTube layout with comments on the right side
- Styled the disclaimer
- When the "Appearance (theme)" setting is set to the "Default" option, it will not change the page theme anymore to the YouTube's theme option after enabling or disabling the ambient light. This is to prevent conflicts with other extensions that customize the page theme.

Fixes
- Restore hidden title in theatre mode with "Hide everything in theater mode" enabled after YouTube's redesign
- Workaround a performance regression Firefox introduced in versions 123 & 124
- Styled the emote menu in the reply form to a comment to still be visible when the "YouTube responsiveness fixed" setting is enabled
