This week we touch on the Vivaldi browser project's take on Google's FLoC. We look at Chrome's vulnerability-driven update to v89, and then its feature-embellished move to Chrome 90. We consider the surprising move by the FBI to remove web shells from U.S. Exchange Servers without their owners' knowledge or permission, and WordPress's consideration of FLoC Blocking. We also have an interesting-looking programmer's Humble Bundle, some interesting closing-the-loop feedback from our listeners, and a brief progress report on SpinRite. We finish by examining an important privacy guarantee provided by Google's FLoC implementation which prevents homogeneity attacks, where users presenting a common cohort ID also share a sensitive attribute.
