Adding openoffice extension

Hello:

I would like to add an OpenOffice extension to Libreoffice writer.
Please let me know if there is a step by step guide that I can use.

Thank you.

The Extension Manager adds, removes, disables, enables, and updates LibreOffice extensions.

Use the Tool - Extension manager menu item, or simply double click on the .oxt file: it will activate the Extension manager feature.

Note: some very old third party OO.o and AOO extensions may not compatible with the LibreOffice.

What extension do you want to install? Where you downloaded it from?
Some browsers may rename the downloaded AOO/LO extensions to .zip (because they really are ZIP archives). Just rename it back to .oxt before you try to install it.

Hello:

Thank you for your response.
I tried to download this extension and use it with Libreoffice.

That is not an Extension, but that is a Template. Just open it with the Writer.
