Apple has released version 5.1.4 of its Safari Web browser, which addresses a number of bugs in the browser in OS X Lion, Snow Leopard, and Windows. The update should be available via Apple's Software Update utility, but can also be downloaded from the Safari Web site.
The update will be between 36MB and 48MB in size depending on the platform you are using, and will require the latest versions of either OS X Snow Leopard or Lion to install; the Windows versions require Windows XP SP2 or later.

As always, be sure to fully back up your system before installing this update. In OS X, updates to Safari include updates to several central frameworks and their support components, some of which are used by other applications and system services. As a result, if a problem occurs with the installation then other programs may be affected, so having a full backup is a recommended precaution.
