Extension Metadata
About this extension
Wissen is a local knowledge collection in the Firefox sidebar. One compact action saves the current page, which can then be categorized, tagged, and annotated. Bookmarks and former knowledge entries live together in one list. Categories can be renamed or deleted; deleting one automatically moves its entries to General.
Search filters titles, URLs, authors, tags, and notes. URL entries can be exported as Firefox bookmarks or HTML, while JSON backups can be exported and imported.
Everything stays local in the browser: no server, telemetry, advertising, or data sharing. The extension never reads page content.
