I've installed Zotero and the Zotero LibreOffice Extension experimentally on a computer which I don't use for research, and I'd now like to uninstall it completely from this computer. I uninstalled all Zotero extensions from Firefox. I know how to hide the Zotero toolbar from LibreOffice Writer, but Zotero it still shows up as a LibreOffice Writer toolbar option when I click on "View/Toolbars."

How can I completely uninstall it from LibreOffice Writer, so that "Zotero" doesn't even show up as a toolbar option? Do I need to completely uninstall and reinstall LibreOffice?

Thanks for the help,
