[$] Content blockers and Chrome's Manifest V3

A clarion call from the Electronic Frontier Foundation (EFF) warning about upcoming changes to the Chromebrowser's extension API was not the first such-from the EFF or fromothers. The time of the switch to ManifestV3, as the new API is known, is growing closer; privacy advocates areconcerned that it will preclude a number of techniques that browserextensions use for features like ad and tracker blocking. Part of theconcern stems from the fact that Google is both the developer of a popularweb browser and the operator of an enormous advertising network so itsincentives seem, at least, plausibly misaligned.
