By default, the latest version automatically enables the notification feature when users close multiple tabs and removes the option from the settings. However, if users still encounter cases where the multiple tab closure notification is not displayed, leading to the loss of important data due to accidentally closing the browser, you can refer to the guide below.
Step 1: Enter about:config into the address bar of the Firefox browser.
Step 2: Type or copy and paste the following line into the search box: browser.tabs.warnOnClose.
Step 2: If the value in the Value box is False, double-click on the value to restore it to True.
Step 3: Continue to locate another value named: browser.warnOnQuit. If the Value column displays False, double-click on the browser to switch it to True.
In addition to creating multiple tab closure alerts to prevent data loss, you can also refer to the article on how to restore recently closed tabs in Firefox, Chrome, and Cốc Cốc introduced by Mytour.
Note that if you choose the startup mode to restore tabs from the previous working session by ticking Show my windows and tabs from last time, Firefox will no longer display multiple tab closure alerts. Therefore, you need to be extremely careful.
