How do I get the old style of the close tab button back?

Hi everyone!
I've checked the settings and can't find an option about the style of the “Close tab” button (maybe I didn't look hard enough).
For me, the new button is small and I want to put its style back. Can you please tell me how to do this?
Thanks in advance!

do you mean the Collapsed Tab X Button?
how can i hide that icon? because sometimes gets annoying, speally when you have the collapsed toolbar on

Seems like it should be set in Zen Mod "Expand on hover", not in browser, sorry!
