Some extensions may not play well with Thunar's on-demand loading and unloading of extensions. For example, an extension that uses a desktop library, which in turn registers additional static GTypes will not work after being loaded and unloaded for the first time. For these kind of extensions, Thunar provides the option to make extensions memory resident, which means the extension will be loaded once and afterwards will never be unloaded again until Thunar exits.

Such extensions must set the resident property of the provider plugin in its thunar_extension_initialize() function to TRUE, using the thunarx_provider_plugin_set_resident() method.
