Yesterday, my 20ish open tabs acted as normal.
The X to close a tab was only present on the active open tab, with the rest not displaying it.
Today, after I updated Firefox Nightly to Version 119.0a1 (2023-08-30) (64-bit), it reopened and now there is no X to close even the active open tab.
I can’t find any setting that controls this, no idea how it happened, but right clicking to close a tab is very cumbersome. Anyone know how to restore the X to close tabs like normal?

This is a bug caused by a refactor / code cleanup. The bug that caused the regression is here: https://bugzilla.mozilla.org/show_bug.cgi?id=1849904
We’ve found the issue and spun up new Nightly builds which should be out
soonnow.
