TabRejoin

Return to existing tabs when you open duplicate URLs. Optionally close duplicates; supports site and page exceptions.

Return to the tab you already have open and keep duplicate pages out of your way. When you open a new tab with the same URL as an existing tab, TabRejoin switches to the existing tab automatically. Set duplicates to close after 1, 3, or 5 seconds, or keep them open. Switching back to the new tab during the delay cancels its automatic closure. Features: • Automatically return to an existing tab with the same URL. • Choose a closing delay or keep duplicate tabs open. • Search within the current window by default, with optional cross-window matching. • Exclude the current site in one click, or add site and individual-page exceptions. • Turn switch notifications on or off and use the interface in English or Simplified Chinese. TabRejoin processes newly opened tabs while the extension is running; it does not bulk-clean existing tabs. Matching is based on URLs, including path case, query parameters, and fragments. All processing happens locally. No account is required, and browsing data is not uploaded. Preferences and exceptions stay in browser local storage.
