Researchers have just unveiled a technique called FROST that lets a website work out which other websites and apps you have open, without you clicking a single thing (protonprivacy.substack.com)

Great. Just what we need.

While it surely can detect whether you're doing something on your SSD, I'm highly doubtful that it could be used to accurately predict what that is. The training model was highly specialized to the target machine and with only certain application genres (e.g. iMac music, videos app store, etc), and only lists two websites (google.com, youtube.com) as identification. In addition, many websites and applications simply don't access the disk.

I seriously doubt there is much that doesn't access the disk drive anymore. Either because of bloat, developer incompetence, or laziness re using code.

Not the I believe they can accurately detect what your doing.

Chrome and Safari will let a single origin claim up to 60% of your disk space without raising a flag

Is it not possible to disable this?
