Chrome appears to be getting support for double-clicking to close tabs
Google browser Chrome appears to be getting support for closing tabs by double-clicking with the mouse or on the touchpad. This is evident from a commit in Chromium Gerrit. Microsoft Edge already has that feature.
The function is called ‘double click to close tab‘ and means users can double-click with the mouse or touchpad to close the active tab. Closing a tab is now only possible with the mouse and touchpad by clicking on the cross. Users can also use a keyboard shortcut.
Google appears to have copied the feature from Microsoft, says Android Police. Edge has had the function for about eight months. This is off by default, but can be enabled via the settings. Before the feature came to Edge, it had been in the works for almost two years. There is already one extension for Chrome which allows closing tabs with mouse clicks.
