Firefox nightly,if i slide less than 70% screen, the tab can't be closed

hey, guys hope someone could understand what I'm trying to talk about. after update to Firefox nightly 144.o1a, in the tab list, i need to slide over 70% to close one tab. feels like i have to very carefully slide it to make sure i really want to close the tab, and it kind of wasting time. the past version like 110.a? are not, easily slide to close the tab. so is there setting in the about: config can change it? like the picture, it have over than it so the tan can be closed.
