If found, simply change the value to true. The action after confirmation allows the user to close the tab page by simply double-clicking on it.

Double-click the tabs one by one to see the function in action. When you do this, one dblclick event is enabled that closes the tab.

The dblclick event is triggered when a pointing button (usually the main button of a mouse) is clicked twice on a single item.

Previously, it was possible to close a tab by installing third-party extensions. As we know, extensions are powerful tools for doing work, but at the same time they can be dangerous, because some people can read users’ browsing history, passwords, emails, etc. without knowing it. If an attacker compromises such extensions, the attacker may have access to the user’s personal data. As such, using the native option in Firefox is a timely step and the most appropriate response to the tamed threat.
