What happened to that extension that allowed one to duplicate a tab?

😎 I just found a list of command shortcuts here: http://www.dori.com/safariShortcuts.html

To duplicate a tab, I found I had to click on the url I want to duplicate to highlight it, then push and hold the following keys until the tab has duplicated (took less than a second):

command shift return

I'm guessing you see them under 'customize tool bar', because you installed both Adblock and Duplicate Tab a long time ago and as long as you haven't rebuilt your Mac by formatting the drive and reinstalling the macOS and all apps, you still have them installed. Neither one comes by default with Safari. You can double-check this under Safari > Preferences > Extensions—if you see them there, as I suspect you will, those are Extensions you have installed.

Another late reply to this thread.

The "complicated" stackexchange link above (https://apple.stackexchange.com/questions/217495/what-is-a-quick-way-to-duplicat e-a-tab-in-safari) also includes the following very simple method which works a treat for me. This is probably why the maker of Duplicate Tab abandoned it.

Cmd/L, Cmd/Return, for me. You don't even need to let go of Cmd. – TetsujinNov 29 '15 at 8:50

I confirmed with Apple this morning that they no longer offer the Duplicate Tab extension icon for the toolbar, they wanted to cut down on all the clutter up there. They came up with any easier way... dragging the URL to the + sign on the end of the tabs section.

So, using my Logitech 2 button + scroll wheel in center mouse, I click on the URL with the left button and hold it while I drag the URL to the + sign on the far right side of the tabs, and PRESTO! 😀 a duplicated page in a new tab appears. That's all there is to it.

However, if you have a different mouse or you're using a trackpad, it's likely different. I'm currently on my desktop so I use the Logitech mouse. When on my MacBook Air it's probably not the same. Will update when I move to my Air with those instructions, if I remember to, that is.

Thanks but I think cmd+L cmd+Return is quicker than grabbing the mouse and dragging onto the + sign. Also the dragging method means you need to have the tab bar showing all the time. The keyboard method works even if the tab bar is not showing.

Some of the commands I found on the list I posted a link to it earlier, do not work anymore, including the one to duplicate Safari tabs. It depends which version of Mac os and Safari you are using. I'm currently using Mac os Sierra 10.12.6 and Safari 11.0. So, I'm highlighting URLs and dragging them to the + symbol on the far right of the tab bar.

Open Safari.

On the top row drop down menus, go to View>Customize Toolbar.

A window will open where your can customize your toolbar with a small selection options. That's where I found it.

However, while looking for this under Safari Extensions, I did a search for it and didn't find it. Not sure if that's because it's already an option under the Customize Toolbar.

I have Yosemite on my MBA, and the latest version of Safari too, so not sure why you don't see it in the Customize Toolbar options window.

So here again, open a new Safari window, click on View on the top menu bar. Then choose the 2nd option -- Customize Toolbar. A drop down window will open. You should see the Duplicate Tab option just to the left of the Address and Search bar. AdBlock is also there, if you want to add that to your toolbar too.

You just click on it and drag it to the toolbar where you want it. See screen shot below:

** You should see the Duplicate Tab option just to the left of the Address and Search bar.

Sorry, I've had a bad head cold for the past week, so I'm not always thinking clearly.

The Duplicate Tab option is to the right (my other left) of the Address and Search bar.

Here is the screen shot when I click on Customize Toolbar and just like the poster, I don't have the duplicate tab icon either...

That's so odd. I just went to check on this again on my Air running OSX 10.10.3 and Safari 8.0.6 and I still see the Duplicate tab option. I also see it in the default set for the toolbar. I wonder why others don't see it. Did you others find it eventually somewhere else?

Here it is... http://thiemo.ch/safari/

It is not listed as an official extension, but works great.
