Keep a copy before you change devices
Open Watchlist and press Create backup. Copy all the text from the output box into a note or document you control. The text contains the saved title identifiers and your manual season-and-episode checkpoints. It does not include video files, account credentials or a playback history from another service.
Restore by merging
On the new browser, open this same OMGFlix website. Paste the complete text into Restore backup and press Merge backup. Known saved titles are added without duplicate list entries. Existing checkpoints in the receiving browser stay in place. Unknown title identifiers and invalid episode values are skipped, with a message describing what happened.
Remember the last finished episode
On a series page, choose the season and the last episode you completed. Save checkpoint records that choice in the browser. This is a reminder you control, not a tracker that watches the player. Update it after an evening of several episodes so the next visit starts with the right information.
Where did the list go?
Private browsing, a different browser profile or clearing site data can leave you without the original list. A home-screen icon does not guarantee that every browser shares storage. Keep your backup before making those changes. Start with Watchlist when you are ready to copy or restore.
