Omnibookmarks is heavily inspired by Hashmem, an extension that is no longer available. Hashmem provided the same approach for saving and opening URLs, but it had several significant drawbacks:

  • Removed from the Chrome Web Store for an unnamed policy violation and was also unavailable for FireFox.
  • Required granting the extension permission to send HTTP requests to several URLs controlled by the author.
  • Not open source, and its JavaScript files were obfuscated.
  • Saved bookmarks using the extension storage API instead of saving them to the browser’s built-in bookmarks database.

So, Omnibookmarks seeks to provide a replacement for Hashmem without these drawbacks.
