I’m trying to customize the tree text colors but I’m unable to inspect it:
There is only
<treechildren xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul" tooltip="folderpopup" slot="treechildren"/> node with no children.
Right now I’m using
userChrome.css from this answer as a template by I don’t know how to modify it to change the text colors.
