YouTube video keeps restarting from beginning — fix the loop bug
A video that should play once keeps restarting from the beginning when it ends. Or scrubbing forward jumps you back to 0:00 unexpectedly. Different from "Loop" mode (which is intentional) — this is unintended re-restart.
Why this happens
- Loop mode is accidentally on (right-click menu → Loop).
- YouTube's "playlist" mode is active and the same video is the only entry — looping by playlist behavior.
- Player session got stuck — fresh video starts treat the previous playback as a new session each time.
- Browser extension forcing replay.
- Memory leak in player state — playhead position resets to 0 on certain triggers.
How to fix it
- 1
Check the Loop toggle
Right-click the player → uncheck Loop. The setting is per-video and resets next session, but the current tab keeps looping if it's on.
- 2
Confirm you're not in a single-video playlist
Check the URL — if it has `&list=...` after the video ID, you're in a playlist. A playlist with only one video loops by default. Strip the `&list=` parameter from the URL and reload.

Disable autoplay
Toggle the autoplay switch next to the player title to off. Some autoplay bugs cause the same video to re-queue and effectively loop.

Hard reload + reopen
Cmd+Shift+R on the URL fixes most stuck-player-state issues.
