Google Chrome gets outdated plug-in blocking
Following the update to 7.0.542.0 in Chrome's bleeding-edge Canary build, Windows users can now turn on outdated plug-in checking. To flip the switch, jump to the about:labs page and click the enable link. Unlike some other experimental features, the plug-in check doesn't require a restart.
Right now, the check is only available in Canary -- but this is the kind of feature Google tends to push to Chrome's other channels in short order.
