Fantastic and the last update is awesome! Been using for ~5 years.

Some problems. Getting false dupes (same domain, different page), and missing real dupes.

would be cool to not close duplicated new blank tabs - i used it as a divider to separate between group of tabs

Maybe could be nice if the equal urls were listed, shown in other window or collapsed/fixed in a group.

Perfect! This is what really I need! Thank you so much!

I love it!

BUG: Doesn't close multiple duplicates automatically when clicking extension button anymore Now you have to click on the extension button every time to close only one duplicate instead of closing all duplicates with one click. Suggestion: Add duplicate count in extension icon

Would it be possible for it to show the URLs of the duplicates upon hovering over the icon, or maybe somewhere else? Also a counter for the amount of duplicate tabs there are would be nice but mainly the URL list. Otherwise great job!
