Joomla extension filter highlights third-party components
Joomla administrators can use a core-versus-third-party filter in the full extension list to identify non-core extensions installed on a site, an inventory view that is particularly useful amid more frequent checks of Joomla websites.
The filter is available in the administrator area under System → Extensions → Manage. It separates extensions listed as part of Joomla’s core from those supplied by external developers, allowing the extension inventory to be narrowed to third-party components.
Why the inventory matters
Third-party extensions are an important part of many Joomla installations, but they also make a site’s software inventory harder to review manually. A focused list gives administrators a practical starting point for checking which external components are present before carrying out broader maintenance or security work.
The view can also help distinguish the software that belongs to Joomla itself from additional packages that may require separate attention. This is relevant as checks of Joomla sites have reportedly become more frequent. The filter does not replace updates or a broader review, but it reduces the effort needed to establish which extensions are installed outside the core set.
For site audits, the relevant path is therefore the complete extension list rather than a separate security screen: open System → Extensions → Manage, then use the filter labelled for core and third-party extensions. Selecting the third-party option provides a quick overview of the externally supplied extensions recorded by Joomla.
