## Description

Bookmark Manager Zero upgrades Firefox bookmarks with privacy-first, on-device processing. It scans folders every 7 days or when expanded, checks live links, detects duplicates, and shows image previews. Edits in Firefox or in the extension sync instantly, with no imports, exports, or extra steps.

Privacy-first by design: nothing is collected, stored, or sent off-device. Optional integrated scans via VirusTotal, Yandex, and Google Safe Browsing use your own API keys stored locally with AES-256-GCM encryption. The extension is 100% free and open source, with customization options and fast search.
