Duplicate Tab Finder

Finds duplicate tabs and closes them in one click, safely. • Keeps the tab you're on and never closes pinned tabs • Optional rules: treat page#a and page#b as the same, ignore tracking params (utm_*, fbclid, gclid) • Hover a rule to preview exactly which tabs it would close • Undo right after closing • Click any tab in the list to jump to it • Light and dark mode. No data collected, nothing runs in the background.
