Google has introduced a feature for automatic updates in its latest Chrome browser but that does not seem to be enough to Google. Therefore, it has gone a step further to add a technology that blocks out of date plugins in Google Chrome, forcing users to upgrade them if they wish to continue using these plugins.

Google has not announced any official time for the release of this feature but it is expected sometime in the next few months. According to this feature, the browser will also show warnings to inform users of lesser-used plugins.

Google Chrome already provides support for an Adobe PDF and Flash by default. Now, Google has taken a step towards security by issuing these updates automatically, which makes Chrome a safer browser. There are some other security features in store for Google Chrome, about which Google says,

There are more ways we are attacking the problem:
Integrated, sandboxed PDF viewing: We have announced an integrated PDF viewer plug-in running inside Google Chrome’s sandbox. This will make it harder for PDF-based vulnerabilities to result in the persistent installation of malware.
Protection from out-of-date plug-ins: Medium-term, Google Chrome will start refusing to run certain out-of-date plug-ins (and help the user update).
Warning before running infrequently used plug-ins: Some plug-ins are widely installed but typically not required for today’s Internet experience. For most users, any attempt to instantiate such a plug-in is suspicious and Google Chrome will warn on this condition.
A next generation plug-in API: Peppermakes it easier to sandbox plug-ins.

Currently, this level of security is offered only by Firefox, which shows update notifications and will auto-update plugins in future.
