I could not even see the problem you warn of, because I do not use Chrome and do not accept cookies. Doubt I will lose files, because I keep files on my hard drive and back up documents, spreadsheets, music and pictures monthly, to a 3 TB Passport.
If you don´t accept cookies, how does it come that you are logged in here?
Don't know. I do not remember making an exception for this site, although I have for certain sites. There are some sites that apparently would like it's users to drop all remaining pretenses of privacy, in order to access their content. I end up dropping, the attempt to connect as there are still options for same or similar content. Not that I have anything to hide, just do not consider my browsing habits, security programs/settings and my hard drive to be any of their business, and certainly not into being data mined for their benefit.
