A small copy of your choices
Open Watchlist and select Create backup. The text box will contain the saved title identifiers and valid series checkpoints. Copy the entire text into a note or document you control. This is a record of your selections, not a movie download and not a NetMovies account. You can keep more than one dated copy if your list changes often.
Restore into another browser
Open this NetMovies site in the other browser, visit Watchlist and paste the complete text into Restore backup. Select Merge backup. Existing saved titles remain, duplicates are not added twice, and an existing checkpoint takes precedence over the imported one. The result message tells you how many titles and checkpoints were added.
Only recognized catalog titles and valid episode values can be restored. Unknown or malformed entries are skipped or rejected with a message. A backup from a different brand is not treated as a NetMovies list. Keep the original copy until you have inspected the restored choices.
Know what is not included
The backup does not contain browser passwords, viewing-service logins, video files, theme preferences, viewing country or recent browsing history. Set the country again on the new device before opening Watch now. If you want to change an imported episode reminder, open the relevant series and save a new checkpoint there.
If browser storage is unavailable, saving or restoring can fail. Read the displayed message and keep the backup text somewhere safe. Do not clear the old browser’s data until you have confirmed the titles in the new one.
