Make a copy before moving
Open My List and choose Create backup. Copy the complete text from the backup field and keep it somewhere you can reach on the second device. It contains saved title identifiers and episode checkpoints, not movies, passwords or a playback account.
Merge on the second browser
Open UFlix’s My List there, paste the text into Restore backup and choose Merge backup. Existing saved titles remain. Duplicate titles are not added twice. An existing checkpoint is kept when both browsers already have a checkpoint for the same show.
If the text is rejected
Copy the whole backup again, including its opening and closing braces. Do not paste a screenshot, a list of movie names or a backup made for a different brand. The message below the field explains whether the text was unreadable or unsupported.
Before clearing browser data
Confirm that your backup restores successfully before removing stored data from the original browser. Private-browsing sessions and device-cleaning tools can remove local choices. A bookmark to My List opens the page; it does not contain the saved items themselves.
