** Automatically detect and prevent duplicate tabs

Preventing and closing duplicates tabs is the core mission. The extension runs in the background, checking when tabs are opened or links are clicked to see whether the target webpage is already open. If open, the extension switches focus to the existing tab, instead of opening a duplicate.

NEW: Quick Tab Search - search, switch to and close tabs. (Similar to ‘Go to tab’)

NEW: List all duplicate tabs, close them directly from list. (For supporters only initially)

COMING SOON: ‘Disappear!’

Tune the core functionality using options - whitelist websites or domains to allow duplicates, or (in beta) use a blacklist to only block duplicates on certain websites.



1. Quick Tab Search (Ctrl/Command + Shift + L)
    - Search and switch to tabs across Chrome windows
    - Close, duplicate, whitelist, or move tab to new window
    - Keyboard shortcuts for all common actions - search, select, switch, close tabs (more coming soon)

2. Direct Switch - ClutterFree highlights links on webpages that are already open in another tab. Clicking a highlighted link switches directly the tab where the link is already open.

3. Open tab count - See number of open tabs on extension button

4. List duplicate tabs (e.g. in switched-off mode, or after installing)
    - Close all duplicates with a direct click
    - Selectively close duplicates
    - Original tabs marked with a special icon

5. Keyboard shortcuts and right-click menu options for quick actions:
    - Open extension window, 
    - Duplicate current tab, 
    - Move a tab to the end,
    - Whitelist pages, and more

6. Detects duplicates suspended by 'The Great Suspender' extension

7. Search tabs from address bar - type `cf` and space to search, and switch to open tabs

8. Detect all pre-existing duplicates, and prompt to close them

9. No analytics or tracking, including Google Analytics

10. Export and import settings to file - to set up different Chrome profiles to same settings

11. Periodic statistics on duplicates prevented, and top domains for duplicates



>> "Read and change all your data on the websites you visit"

This phrase above is how Chrome describes when an extension uses the 'tabs' and "all_sites" permissions.

The extension needs these permissions to manage tabs - checking for, preventing, and closing duplicates.

  • One must have imo. Sometimes duplicate is not functioning well. The new tab created is treated as a normal duplicate tab and closed instantly.
