The Joomla Extension Manager handles installation, updating, and removal of all extensions — components, modules, plugins, templates, and language packs. Joomla 6 supports installation from a URL, an upload package, a local folder, or the official Joomla Extensions Directory (JED) directly from the admin panel.
Installing Extensions
Go to Admin → System → Install → Extensions. Four installation methods:
| Method | Best for |
|---|---|
| Upload Package File | ZIP downloaded from a developer's site |
| Install from URL | Direct ZIP link — avoids local download |
| Install from Folder | Files already extracted on the server |
| Install from Web | Browse and install directly from JED |
Managing Updates
Go to Admin → System → Update → Extensions. Joomla checks all installed extensions against their update servers. Extensions with available updates are listed with a one-click update button. Run Find Updates to refresh the list.
Manage Tab
The Manage tab lists every installed extension. From here you can:
- Enable / Disable — plugins and modules can be toggled without uninstalling
- Uninstall — removes files and database tables
- Edit — open the extension's configuration
- Filter by type — component, module, plugin, template, language, file, package
Database Check
After installing or updating extensions, run Admin → System → Maintenance → Database to check for schema mismatches. Click Fix to apply any pending SQL updates that were missed during installation.
Discover
The Discover tab scans the server for extension files that were uploaded manually (e.g. via FTP) without going through the Extension Manager. Select discovered extensions and click Install to register them in the database.
