Safari tabs grouped by site in TabCaptain

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 TabCaptain
