These are created by 3rd party developers.

Select Extensions from the Install Panel in the System Dashboard.

Protect your website when using 3rd Party Plugins

Take the following steps to protect your website when installing and uninstalling plugins.

  1. Back up your website before installing a plugin.
  2. Check for vulnerabilities on the Joomla! Vulnerable Extensions List.
  3. Only download plugins from trusted sites.
  4. Test a plugin on a development site before installing on your live site.
  5. Next test a plugin on your live site (you may wish to check logs for runtime errors and warnings).
  6. Remove any junk files from the tmp directory following installation of a plugin.
  7. After uninstalling a plugin, check that all related folders, files and database tables were removed by uninstall scripts.1
  8. Periodically check for new releases and update installed plugins.
  9. Check with the third party developer that there are no restrictions relating to use of their plugin.
