Change default Tab closing behavior in Firefox browser

Mozilla Firefox browser by default switches to next tab when you close the current tab. This default behavior is not preferred by users who have multiple tabs opened and would want to access the last tab after closing the current tab. An extension that can manage this viewing order of opened tabs or allows customization can make the browser much more logical for use. Select After Closing Current is a Firefox Add-on that will help you configure which Tab to select after closing the current tab. It helps you change the processing rules for a closing tab.

Change default Tab closing behavior in Firefox browser

Select After Closing Current Firefox extension has one shortfall. It has options that seem confusing. Plus, the extension restores original behavior i.e., it starts switching to the right tab and then moves to the left tab. This is mainly because Firefox 57+ compatible extensions cannot access Firefox’s internal working, so the browser’s default selection cannot be prevented. This extension, however, fixes it quickly afterward.
