How to make addons work on the blank new tab?

i tryed browser.tabs.selectOwnerOnClose but it doesnt work

What exactly do you want to have working? In general the content of about:blank (the blank page) is not accessible to extensions iirc

i want extension “Close Tab by Double Right Click” to work on blank pages. i dont know why but i very often open this blank pages, but my favorite extension dont work on them, this is very annoying)

excuse me i said wrong i need this extension to work on new tab page
