The Chrome Web Store rounds user counts down to the leading digit, so the user line moves in steps. The ratings count is exact and is the better signal of real adoption.

About Tab Deduplicator

Tab Deduplicator prevents you from accidentally opening the same URL in multiple tabs. Instead of cluttering your browser with duplicates, it automatically detects when a tab with that URL already exists and redirects you there — whether you paste a link into a new tab, click a link from an external app (Slack, email, etc.), or open it any other way. You stay in full control: the extension only works for URL patterns you explicitly configure. Everything else opens normally. Features: • Wildcard URL pattern matching (e.g. *.salesforce.com, github.com/myorg/*) • Works for paste-and-navigate, Cmd+click, and links from external apps • "Add Current Tab" button to quickly register a domain • Patterns synced across Chrome profiles via Chrome Storage Sync • No data collection — all processing happens locally in your browser
