Close tab button without a icon

[gabriel58827]

Basically the title. I just installed the alternative version of the theme (-a) and the icon to close the tab is not there. I removed the theme and reinstalled and it did not appeared. Tried installing the other versions of the theme and it stayed the same).

Also had this problem. Quick fix is in /chrome/[theme name]/parts/tabsbar.css
Quick fix is to delete .close-icon and .tab-close-button
I've also made a version of the code that works using the basic Firefox icon, that you can just copy paste

/* Close tab button */
.close-icon {
	height: 16px !important;
	padding: 2px !important;
	width: 16px !important;
}

.tab-close-button {
	-moz-appearance: none !important;
	margin-inline-end: 0 !important;
	border: none !important;
	box-sizing: content-box; /* Avoid deformation on flexbox */
	border-radius: 3px !important;
}

I think it might be a way to fix this without removing the custom icon, but I do not understand the code well enough. This quick dirty fix should be fine though.

(I've tested this on LibreWolf, with sidebar and top tabs)
