Accidentally press 0-9 on YouTube and lose your place? YT Timestamp Undo saves your timestamp before every number-key skip and lets you jump straight back.
When you hit 0-9, YouTube jumps to 0%-90% of the video. This extension remembers where you were and shows a small popup in the corner: "Number-skip: 12:34 -> 4:30" with a Go back button. Press Backspace or click the button to instantly return to where you were.
