Google recently updated its Chrome browser in order to fix a major security problem. The problem affects the mainstream stable version of Chrome and is fixed in the new version 1.0.154.59.  Chrome is built to automatically update itself, so users should receive this update without having to do anything. The update will require the software to be restarted before it takes effect. Should you need to manually force the download, you can do so by clicking the wrench icon in the upper right corner of the browser,
