When closing a tab, fulguris always goes back to the original tab, and I want to automatically switch to the unviewed tab

[chwt163]

When I open a website, then open multiple links to this website as a new tab in the background, then view the newly opened tab, and then close, at this time, fulguris always goes back to the original tab, and I need to manually select to see the tabs that were previously opened in the background.
I want to automatically switch to an unviewed tab when I close it.
