Close Duplicate Tabs

does not work for me, nothing closed

doesnt work for me 1. for single window having multiple duplicate tabs 2. for multiple windows having multiple duplicate tabs

No bad, but does not match urls with different parameters.. For example a google doc with a different anchor in url.

Lacks any settings similar to Duplicate Tabs Closer which granted features like dictating which tab to keep in instances such as individual duplicate closing, choosing to keep older or newer tab, automatic duplicate closing (no clicks required), etc. This is a good start but needs more work to keep up with the original.
