Tabwatchdog

Prevent duplicate tabs and keep your browser tidy. Automatically redirects you to existing tabs instead of opening new ones.

TabWatchDog keeps your browser clean and clutter-free by watching for duplicate tabs as you browse.

KEY FEATURES

• Duplicate Tab Prevention
Navigate to a URL you already have open? TabWatchDog instantly switches you to the existing tab and closes the duplicate — no extra clicks needed.

• Merge All Windows
Spread across multiple browser windows? Use the "Merge All Windows" button in the popup to consolidate everything into one window, with duplicates removed automatically.

DESIGNED TO STAY OUT OF YOUR WAY

TabWatchDog works silently in the background. No popups, no interruptions — just a cleaner browser.

KNOWN LIMITATION

Tabs that go through multiple redirections (e.g. SSO or OAuth login flows) may not be detected as duplicates. This will be addressed in a future update.

Version 1.7

Bug Fixes & Safety Improvements

• Fixed: "Installed Successfully" notification was appearing on every browser
restart, not just on first install.

• Fixed: Clicking the extension icon no longer instantly merges all windows
with no warning — it now opens the extension popup instead.

• Fixed: view-source: pages are no longer incorrectly flagged as duplicate
tabs of their underlying page.

• Improved: "Merge All Windows" now requires an explicit confirmation before
making any changes, preventing accidental merges.
