Google is essentially saying that Chrome will still have the capability to block unwanted content, but this will be restricted to only paid, enterprise users of Chrome. This is likely to allow enterprise customers to develop in-house Chrome extensions, not for ad blocking usage.
For the rest of us, Google hasn’t budged on their changes to content blockers, meaning that ad blockers will need to switch to a less effective, rules-based system, called “declarativeNetRequest.”
I’m glad I switched to Firefox already, and I suggest you do the same. A browser that is not tied to a platform vendor (like Safari) or run by an ad company (like Chrome).
