Google Bookmarks has an authentication problem that they have yet to acknowledge. It affects all systems, all browsers including Internet Explorer, and all versions of software. The problem appeared about three or four weeks ago. Users around the world have lost access to their Google Bookmarks because Google can no longer recognize their passwords. I'm not sure what happened, but it happened at the Google server, and you cannot fix it by updating your system. No one can. Google has to address this problem. I'm wondering why we haven't seen some official response from Google on this serious issue.
