Bookmark Groups от Vampire

Organize your Firefox bookmarks into Linux-style folders on the New Tab page. Create folders, drag bookmarks into them, search across all bookmarks, and navigate with an expandable sidebar tree. Import existing Firefox bookmarks with folder structure preserved. Add new bookmarks directly with name and URL. Edit, rename, delete, or move items via right-click context menu. All data stored locally via browser.storage. No tracking, no analytics, no remote code.
