Absolutely beautiful, thank you so much. This was the deciding factor for me to switch to firefox all the way. It's really odd how is this not native functionality.

Thank you so much. I don't need to 'right click the tab and hit D' anymore. 🤓

This Extension works really well. I was using to Pop-Out Selected Tabs into a New Window. It works, but I don't know how the code is written in the background, but the Tabs take a long while to Load and Appear in the New Window. I recently found another Extension "Tab Shortcuts" that I'll be testing out.

I needed this extension to easily create new tab as a child of current in TreeStyleTabs with saving current tab MultiTabContainer to replace duplicated URL by new search request. And this extension worked good, except that Alt+Shift+D is a counter intuitive shortcut for me if even a convenient one (more convenient than Ctrl+Alt+D). But next I found Vimium and it could "create new tab as a child of current in TreeStyleTabs with saving current tab MultiTabContainer" just by pressing t and it was new tab with opened URL search, not just duplicated (though shortcut for duplicated was just yt and TreeStyleTabs and MultiTabContainer were ok too). So I delete this extension for both easier and more functional one (and better matching to my actual goal).

I keep thinking I can replace this add-on. Unfortunately, this is not true. Once you have grown accustomed to the ease and power of this add-on, there is no other add-on that can possibly replace it.

Doesn't work on Manjaro KDE with FF 122.0.1

Edit: Works now after reassigning the shortcut because alt+shift+d was already in use by another extension (Dark Reader). Would be five stars if it was possible to toggle whether to switch to the duplicated tab.

Edit2: FIVE STARS AND A SEAL OF APPROVAL!

(There's a bug where the "Open new tabs in the background" feature doesn't seem to work with "New tab to the right" no matter what shortcut I try to assign to it)

Does just about it.

Nice and fast I used ctrl+shift+v. almost every single shortcut is already taken so youhave to be creative.

go into the settings tab to change keys

Amazing, I love it.

If you need ideas for keybinds, I suggest Alt-T to duplicate tab, Alt-N to pop tab to a new window.

To me the 'Pop tabs to a new window' is as important, if not more important than the 'Duplicate tab' shortcut, so the name of the extension is unfortunately a bit misleading..

It works for what I wanted it to — duplicating tabs with a hotkey — so I am completely satisfied. And, on top of that, it also supports a hotkey for another great feature: new tab to the right. This extension is amazing, I love it.
