Duplicate Tab in Firefox and Internet Explorer 7 (IE7)
Contributed by MickeyMouse 
Tagged: Browsers Duplicating tabs in both of these browsers is accomplished the same way. Here’s the shortcut to do it.
As much as they are different, these two tabbed-browsers do a lot of things the same. The most useful thing in common is the shortcut to duplicate a tab. Here’s how…
1. Open either firefox or IE7
2. Click in the address bar
3. Press ALT-ENTER
4. Your current tab will be duplicated.
Yes, this works in both tabbed browsers.

I will say thank you, because I never knew how to do this and this helps a lot. But I wish there was a way to duplicate the tab AND keep the history for that tab. I remember a long time ago in the IE 6 times, you could open a new window with the same URL and history as your current one.

Does not duplicate the history, tho. Just the current page.
Ctrl+N duplicates history and everything but in new browser iteration.
Would love to see that in a duplicate tab.

Works indeed, but history is not duplicated. For that, press ctrl-key while dragging tab accross; works for FF only.

Instead of step 2. (Click in the address bar) you can do Ctrl+L

ctrl + k works in ie9 but ctrl + d instead opens a favorite dialog box in both browsers.

There’s ANOTHER way to DUPLICATE TABS:
While holding down the control key (Windows), click and drag the desired [TAB] over into the blank space next to it.
CHEERS

IE9 have a new “duplicate tab” functionality that keeps the back history as well! Right click any tab and click duplicate tab!
