Firefox Nightly 119.0a1 (2023-08-30) (64-bit) now has no Tab Close X buttons!
So with yesterday's update, the close tab button has been removed from tabs unless the tab is in it's own window. Have more than one tab or a lot of tabs? you will no longer see the Close tab X and are forced to right click on the tab and select Close. This is annoying and weird as usual. Please fix. updates should improve not devolve a product lol
