Create the copy
- Open My List in the browser with your saved titles.
- Choose Create backup.
- Copy all of the text from the backup field.
- Keep the text in a note or document you control.
Merge on another device
Open My List in the destination browser. Paste the entire text into Restore backup and select Merge backup. Existing checkpoints in that browser are retained. Read the result to see how many saved titles and checkpoints were added and whether any unknown entries were skipped.
If an import fails
Check that you copied the whole backup, including its opening and closing characters. A screenshot of the text cannot be pasted as a working backup. Do not invent missing characters. Return to the source browser and create a fresh copy if it is still available.
The backup contains catalog references, not video files or sign-in credentials. It cannot recover local data that was cleared before you kept a copy. A normal browser profile and a private session have separate lists, so confirm which one contains your choices before you start.
