- by Firefox user 17422434, 4 days agoRated 1 out of 5Hours gone to waste because of this piece of crap. Instead of closing just duplicates, it closed all tabs that I had 2 or more of open. So for example, I had two copies of a tab. It closed them both. Ctrl-shift-T only goes back so far. I'm going to have to start all the way back at the beginning now. I can't even express my rage at this useless extension. I completely regret I ever got it.
- by jesus2099, 4 months agoRated 3 out of 5It's super great but I have an issue now on Linux Firefox 91. Duplicate Tabs requires Containers, that I deactivate. Containers, when activated for Duplicate Tabs, hinder my right-click, C keyboard shortcut to quickly copy URL of a link, which I need every 5 minutes. I had to deactivate this extension, sadly...
- by NC, a year agoRated 4 out of 5This Extension is nearly perfect! The best of the duplicate tab closing extensions on Firefox. I would love to see a couple features that I think would push this into the perfect 5* range.
 Whitelist should be available with the 'do nothing' option so that it applies to the "Close All" button as well, so that I can exclude certain pages (such as New Tab or about:blank) but still use that option.
 Add the option to pop up a Notification on duplicate. Automatically removing tabs has caused me issues, so I do not use that feature, but I still would love an option to know when I am duplicating an existing tab in the moment.
 In the duplicate tab notification window it would be nice to have the options to close New or Old duplicated tab, or to do nothing.
Thanks for all the hard work!
