I think it would be nice to implement the Firefox-Sweet theme, because garuda dragonized is themed in the Sweet Theme (with the optional modifications of "hide-single-tab.css" and "matching-autocomplete-width.css")
but as i've tested it, it seems to have some issues (min, max, close window buttons are not displayed with disabled titlebar) so if this would be a choice / option to be added, it might be needed to alter the theme (however, this might be a issue with LibreWolf itself, because it works with Firefox)
the link to the theme:
