Wikidata од Shisma

"Wikidata for Firefox" is a browser extension that allows users to easily access information from Wikidata while browsing the web. Wikidata is a free, collaborative, multilingual knowledge base that can be read and edited by both humans and machines. It contains structured data that can be used to support Wikipedia and other Wikimedia Foundation projects, as well as external projects and initiatives.

The "Wikidata for Firefox" extension adds a button to your Firefox toolbar that, when clicked, displays a sidebar containing information from Wikidata related to the page you are currently viewing. This can include information about people, places, and things, as well as links to related Wikipedia articles and other resources.

The extension also allows users to edit Wikidata items directly from the sidebar, making it easy to contribute information and help improve the accuracy and completeness of the knowledge base.
