In "QuotaManager IO" thread, the names of most the websites are still present even after sanitizing the profile. This effectively means that anyone can look at the profile and see what all websites I have visited

Unsanitized profile: https://share.firefox.dev/4txSs9b
Sanitized profile: https://share.firefox.dev/3QMzblV

Notice that in the sanitizzed version, the pathnames are removed, but teh name of the db/wal/whatever files are still present. These db/wal/whatever files have the same name as the website.
So effectively, if I share a sanitized profile, anyone can see which all pages I visit.

This seems bad.
