Firefox 3 to feature tab duplication
Firefox 3 will let you duplicate currently opened tabs. This may come handy for those times when you need to split navigation but need to keep a copy of where you started, or are about to take action on a web page that may change it and want to keep a reference.
Whatever the reason, you will just have to press the Ctrl (Cmd on Mac) key while dragging the tab you want to duplicate and dropping it where you want it to appear. To visually differentiate from plain old tab moving, the mouse cursor changes to a copy cursor with a cross.

So far, there is no user interface such as main menu or context menu item to duplicate a tab. Also, note that the duplicated tab doesn’t inherit the original tab’s history.
Noticed the ghost tab in the screenshot? It is a new visual trick for all dragged elements and will also be available for massive consumption in Beta 2, later this month.
If you want this feature now, you may want to try Duplicate Tab, a Firefox extension that provides this same feature for Firefox 2.

You have been able to duplicate tabs in Opera for a long, long time.

I have this feature on Firefox 2(Just tried dragging a tab with Ctrl and it was duplicated), but i don’t have the Duplicate tab extension.
Maybe TabMixPlus has this?( i use that one)

maybe clicking the scrool button on the go button is enough?

Working on my Firefox 2 too. Maybe due to the Tab Mix Plus extension. ^^

Use of Ctrl+Drag Tab has more of a Windows feel to copying tabs than using the Tabs Context menu in “Duplicate Tabs”. Good to see some of the functionality of the extension available Firefox 3. (tested in Fx 3.0b5pre)
Features Ctrl+Drag tab to an empty tab position, between other tabs, immediately before first tab, or anywhere after the last tab.
I hadn’t even realized “Duplicate Tab” already had the feature with the Ctrl+Drag Tab for placement, so this may remain a bit obscure in Firefox 3.

Is there any plans for adding a context menu item for this? Cant find anything related to this feature in Bugzilla.
The duplicate tab extension is great, but i would really want to see this funcionality as default in Fx3. Merging windows would also be great.

Hmm, great that this finally is possible in FF3. Too bad we still need an (yet to be developed…) extension to be able to press for instance Ctrl+T (or Ctrl+Alt+Shift+T) to clone the tab without needing to Ctrl+drag…
Anyone know if or when such an extension (or even core feature) is available?

The “Duplicate Tab” extension has hotkeys for duplicating tab (for duplicating tab to tab, duplicating tab to window, detaching tab, and merging windows).

Additionally, you can combine “Duplicate Tab” (or the similar “Clone Tab” extension) with “keyconfig” to change those hotkeys.
While it’s not documented, Cntrl+Shift+T executes a duplicate tab when using “Duplicate Tab”. The documented key combo for that operation “Cntrl+Shift+U”, which is nicer when using two hands.

Unfortunately, as of FF3 RC3, this feature doesn’t work in OS/X (i.e., “Cmd” is not supported).
So, no duplicate tab for me. :(
