BookMacster is a bookmarks manager for your Mac, which plays nicely with iCloud, Sign In to Chrome, and Firefox Sync. It can be used in three ways, or all three:
Manage Browser Bookmarks. Add alphabetizing and tagging. Verify, fix dupes, consolidate.
Cross-Browser Syncing. Sync bookmarks of Safari Firefox, Chrome, and more among all your devices.
Directly. Keep your bookmarks in one central store, accessible within web browsers.
