Every few days, Chrome will freeze. I force quit, and then when I reopen it, I've lost all of my cookies and saved passwords. This has been happening for a few months.

I'm signed in and I have sync enabled.

Sorry I don't have better information, I'm hoping someone will recognize this if it's a duplicate of a similar bug with more information.
