Yes, Firefox has never done that.

Firefox has a couple ways to duplicate the current tab into a new tab:

• Ctrl+click the reload button -- on Mac it's probably Command+click
• Ctrl+drag the tab along the tab bar to duplicate it -- on Mac, it's probably Command+drag

Over the years, people also have created add-ons to add this feature to the right-click context menu of a tab, or a toolbar button.

But I'm not aware of either a built-in feature or an add-on for duplicating the current page into a new window or new private window.

Okay, I searched a little harder. Maybe:

• https://addons.mozilla.org/firefox/addon/duplicate-2-window/

Thank you but I installed this add on and I could not get it to work. How do I use it?

Control click worked on my Mac, thanks Sir!

Thanks for the update. I think Ctrl does something very different on Mac than Windows if you get a new window, but I'm glad to hear you found something. Could you mention what it is you're Ctrl+clicking on?

jscher2000 – I'm Control Clicking on any part of the page that I want to duplicate a website and that action opens up a small pull down menu at the point of the click – "Save page as; Duplicate; and Duplicate in Private Mode" This solves my problem after so many years of frustration of cutting and pasting the url, thanks again – EasyRyder
