If you’re unable to scroll down while watching YouTube in full-screen mode, that’s expected behavior—full-screen is designed to show only the video, not the page or comments.
But if you mean the scroll isn’t working when you’re not technically full-screen, here are two situations to clarify:
✅ Situation 1: Normal Full-Screen (Expected Behavior)
When you hit the full-screen button (or press F), the video takes over the whole screen—this hides the rest of the page (like comments or sidebar), and you can’t scroll.
➡ Solution: Press Esc or click the full-screen icon again to exit, then scroll normally.
🚫 Situation 2: Theatre Mode or Zoomed Layout—Scroll Broken
If you’re not in true full-screen, but you:
-
Use theatre mode (wide video, not full screen),
-
Or zoomed in using browser zoom (
Ctrl +), -
Or fullscreen on mobile but can’t scroll comments,
…yet scrolling is broken, that’s likely a bug or browser issue.
✅ Fixes for Scroll Not Working (When It Should)
1. Refresh the Page
-
Often resolves temporary rendering glitches.
2. Exit and Re-enter Theatre/Full-Screen Mode
-
Click the mini-player/full-screen/theatre mode icon to toggle.
3. Check Browser Zoom
-
Reset zoom to 100% (
Ctrl + 0orCmd + 0). -
Excessive zoom can interfere with scrolling layout.
4. Disable Browser Extensions
-
Ad blockers, video enhancers, or scripts can break layout or scroll behavior.
Try in incognito mode or disable extensions one by one.
5. Update Your Browser
-
Make sure Chrome, Firefox, Safari, or Edge is fully up to date.
6. Try a Different Browser
-
Sometimes it’s a rendering bug specific to one browser.
7. Clear Cache/Cookies
-
Go to your browser’s settings and clear cached site data for YouTube.

✅ Mobile-Specific Tips
On the YouTube app (Android/iOS):
-
Full-screen mode won’t let you scroll—tap the video to show controls, then tap the square icon to exit.
-
If you’re not seeing comments even outside full-screen, force-close and relaunch the app, or update it via the App Store / Play Store.
