I don't use bookmarks in my browser. If there is information on a web site page I want to save I simply store and tag it in Evernote. And that is available from any device or browser on any platform.
I'm having other problems with Google Chrome on my Mac ( my son prefers it because he needs flash for certain legacy web sites ). It keeps inserting itself into my login items and I've noticed it keeps a process running. Even if I reboot the machine I find a background Chrome process.
