close duplicate url tab (reduce to one each)

[nanotonne]

i like find all duplicate tab, it's easy, but how to close duplicate tab (not all tab selected) ?

please add this feature, example :
we click on "highlight duplicates" button
we click on new button "close all duplicate tab from selected" <----- this new feature
and result : we have only one tab url each, other same are close (or unselected?), others duplicates are close

firefox have this feature but only for each window, not for global, if same url (tab) is found in various windows, unable to close other tab of window to have only one.

before :
window 1
tab with url1
tab with url2
tab with url3
tab with url1
window 2
tab with url4
tab with url5
tab with url2
tab with url1
window 3
tab with url6
tab with url1
tab with url7
tab with url5

(....)

after :
window 1
tab with url1
tab with url2
tab with url3
window 2
tab with url4
tab with url5
window 3
tab with url6
tab with url7

thank you!

I would love this feature as well! I often have like 50 duplicates (maybe 15 unique tabs), and I just want to leave the unique ones open and close the rest.
