See repeated URLs together

The duplicate view groups matching pages by site, so repetition is visible instead of hidden across windows.

Review before closing

Keep the copy you still need and close extras individually. The source page remains visible in the group.

Close all duplicates with Premium

Lifetime Premium unlocks the bulk duplicate cleanup action for a faster reset when the review is straightforward.
