YouTube Queue Button Restore
Restores the "Add to Queue" and "Watch Later" hover buttons on YouTube video thumbnails — removed by YouTube around 2026年03月27日.
What happened?
YouTube silently removed the overlay buttons that appeared when hovering over video thumbnails on the homepage and subscription feed. These buttons ("Add
to Queue" and "Watch Later") are now buried inside the three-dot menu, requiring extra clicks.
This userscript brings them back.
Features
- Hover overlay buttons on every video thumbnail — just like before
- "Watch Later" (clock icon) — saves the video to your Watch Later playlist
- "Add to Queue" (list icon) — adds the video to the playback queue
- Visual feedback — button flashes green on success, red on failure
- Works on all YouTube pages — homepage, subscriptions, channel pages, search results
- Handles both old and new YouTube DOM — YouTube uses different internal structures on different pages; this script handles both
- Shorts excluded — buttons are not injected on Shorts thumbnails
- SPA-aware — works across YouTube's single-page navigation
- Infinite scroll support — buttons are injected on dynamically loaded content
- CSP / Trusted Types compliant — no
innerHTML usage; safe on YouTube's strict CSP
How it works
When you hover over a video thumbnail, two small buttons appear in the top-right corner:
| Button |
Icon |
Action |
| Watch Later |
🕐 Clock |
Saves to Watch Later playlist |
| Add to Queue |
📋 List+ |
Adds to playback queue |
Internally, the script programmatically triggers YouTube's own three-dot menu (hidden off-screen) and clicks the corresponding menu item. This ensures
full compatibility with YouTube's internal state management — the queue updates, toasts appear, and everything works natively.
Requirements
- A Tampermonkey-compatible userscript manager (Tampermonkey, Violentmonkey, etc.)
- YouTube desktop web (youtube.com)
- Must be logged in to YouTube for queue/watch-later functionality
Known limitations
- Buttons are language-dependent — currently matches Japanese menu items (「キューに追加」「後で見る」). If your YouTube is in a different language, you
may need to edit the keyword strings in the script.
- There is a brief processing delay (~200ms) when clicking a button, as it waits for YouTube's internal menu to open.
Changelog
v1.0 (2026-03-28)
- Initial release
- Supports both new DOM (
yt-thumbnail-view-model) and old DOM (ytd-thumbnail)
日本語
YouTubeが2026年3月27日頃にサムネイルホバー時の「キューに追加」「後で見る」ボタンをサイレント削除しました。このスクリプトはそれを復活させます。
サムネイルにマウスを合わせると、右上に2つのボタンが表示されます:
- 🕐 後で見る — 「後で見る」プレイリストに保存
- 📋 キューに追加 — 再生キューに追加
内部的にはYouTubeの三点メニューを不可視で操作しているため、YouTubeネイティブの動作（トースト通知、キュー更新など）がそのまま機能します。
