Google’s Proposal for Chrome Browser Threatens Ad Blockers, Developers Say

A Google proposal that could make it harder to block web ads has prompted complaints from developers offering such tools.

Google is working on a change to its Chrome browser this year that would limit how browser extensions built by outside developers can interact with websites. It’s aimed at improving security and privacy for Chrome users. But some ad blocker software makers say the move will render their tools useless, while benefiting Google’s online advertising business.
