/primary/ was a primary-resources hub page in the prior palancar.net catalog — most likely a curated index of the prior owner’s most-trafficked Firefox extensions, audio plugins, and music releases. The present editorial directory at palancar.net is operated by a different team. The Firefox extensions documented from this hub are now in our extensions section in editorial form; other prior-owner content is not within the current vertical. The original /primary/ snapshot is in the Wayback Machine archives. URL preserved for backlink continuity.
