The Extension Manager adds, removes, disables, enables, and updates LibreOffice extensions.
For security reasons, the installation and removal of extensions are controlled by settings in the Expert Configuration. By default, installation and removal are enabled.
The following are examples of LibreOffice extensions:
UNO components (compiled software modules)
Configuration data (for menu commands)
LibreOffice Basic libraries
LibreOffice dialog libraries
Extension files (*.oxt files containing one or more extensions of the above listed types)
The availability of an extension depends on the location where you add the extension.
Extensions that you add to "LibreOffice Extensions" are available to all users. You need administrator rights to add to "LibreOffice Extensions".
Extensions that you add to "My Extensions" can only be used and managed by yourself.
An extension is available as a file with the file extension *.oxt.
You can find a collection of extensions on the Web. Click the "Get more extensions online" link in the Extension Manager to open your Web browser and see the https://extensions.libreoffice.org/ page.
Do any of the following:
Double-click the *.oxt file in your system's file browser.
On a Web page, click a hyperlink to an *.oxt file (if your Web browser can be configured to start the Extension Manager for this file type).
Choose Tools - Extension Manager and click Add.
As a user with administrator rights, open a terminal or command shell.
Change to the \/program folder in your installation.
Enter the following command, using the path and file name of your extension:
\<item type=\"literal\"\>unopkg add \</item\>\<item type=\"literal\"\>--shared \</item\>\<item type=\"literal\"\>path_filename.oxt\</item\>
