Duplicate Tab 作者: Skeletonxf

No more CTRL+L CTRL+C CTRL+T CTRL+V to get your tab open a second time!

Just use ALT+SHIFT+D to duplicate your current tab.

Shortcuts can clash with default Firefox shortcuts unfortunately, in which case Firefox's shortcut will take priority and your custom one will not work. Shortcuts can be customised at the about:addons url.

With Firefox 57 released in 2017 a duplicate tab menu option on the tab menu was added by default. You can still use the button or tab right click menu from this addon to duplicate tabs. Configuring this add on's switch focus will not affect the default Firefox duplicate menu option.

Please note that most functionality is not possible on Android at the moment due to limitations in Android's APIs (no keyboard shortcuts). Duplicate Tab is written so that if the APIs become available in later releases then the features should automatically become usable without an update to Duplicate Tab needed.
