Duplicar pestañas nunca había sido tan sencillo pero si tiene la versión 22 de firefox recomiendo Duplicate This Tab mientras lo actualizan.

Duplicate Tabs Rated 1 out of 5 stars

I agree with Mike Clark below. This is simply an automatic drop down button on most browsers under either file or edit. Why make this so complicated?

Work Around for Current Firefox Version

Duplicate This Tab: Hold CTRL Key Down & Move Tab with Mouse. Works great for FF 10.0.2

Most useful extension I use Rated 5 out of 5 stars

Without a doubt this is the one extension I hold off upgrading for. It is, by far, the most useful add-on I use. Once you get accustomed to using it, it is very hard to be without it. I agree with several others; IT SHOULD be an integral part of Firefox. Please keep it updated. Thanks.

Making This Available Again Rated 5 out of 5 stars

Duplicate Tab 1.0.2c no longer works now that Firefox has reached Version 10.0.1 . Duplicate Tab Version 99.0 still works but its distribtuition vehicle, megaupload.com, has been shut down by the FBI, apparently for violations of law. I have a copy of "Duplicate Tab Max Version 99.0.xpi". As Duplicate Tab is being kept alive by its users and no one is losing money thereby nor, as I understand it, is it copyrighted, if someone will post it on the web for us and put the link here, I will be glad to send it to them for that purpose.

This Extension should definately be a part of Firefox as it is integral to Firefox's use.

it's perfectly working on 9.0.1 !
btw I would like to customize the toolbar button, I tried with the chrome.css using "duplicatetab-button"
but I failed, please may I have the right "identifier" (i.e. for Brief the identifier is #brief-button )
thanks in advance !

Duplicate Tab Max Version 99.0 download link : http://www.megaupload.com/?d=LY2X5UPT
(Tested with Beta8.0,Release7.0)

@Empatojayos : Why don't you just clone it and upload it to this site,and maintain it yourself,the original creator has obviously abandoned this add-on.I set the max version so high so people won't have to bother looking for an update,since there has not been one from Twanno in a very long time.I have been using this add-on for a few years now and It works fine with every Firefox release so far...with add-on compatibility reporter installed.If it stops working...find a suitable replacement that is maintained.

(Tested successful in FF7.0.1 stable, FF8 beta 1, FF9 (aka Aurora) alfa 2, FF10 (aka Nightly) alfa 1) Only-32bits.

This feature should be built into Firefox. IE, Chrome, and Opera all have a built-in duplicate tab menu item. Anyway, the plugin works well, does what it says it does, and the extra configurability is appreciated. One request: I'd like the option to hide the keyboard shortcut hint in the menu.

Many thanks to Empatojayos, would not live without that little tool

this is one of my favored extension, and Empatojayos's modification works perfect on FF 6
its a shame that the official extension is not supported any more.

Seems to work ok in 5.0.1 Rated 5 out of 5 stars

I updated the rdf file (Google "edit an xpi file") to max version 9.9 and it appears to work just fine in Firefox 5.0.1 on my new Windows 7 64-bit machine. This is great news since I love this add-on, especially that it duplicates the history of the tab as well.

Use "Duplicate this tab" Rated 5 out of 5 stars

For those wanting an updated version of this, someone has made an updated version called "Duplicate this tab".

Just a straight code copy but with latest browser support.

Thanks Rachel, can we do the same for version 3.6.6? What is the path to the "install.rdf" and to edit it do I just open it? Thanks!
