Attention surfer girls (and boys): Apple has released Safari 5.0.4. The new version of the company’s Web browser contains numerous stability, compatibility, accessibility, and security improvements. Web pages with multiple instances of plug-in content, image reflections, and transition effects should all work better. An issue that caused some Web sites to print incorrectly is fixed, too. Also fixed are VoiceOver bugs and an issue where the screen saver could appear while watching video in the browser. Additionally, the update patches more than 50 security vulnerabilities.

Turn Off Filename Extension Warning
In Leopard, Apple fixed an annoying aspect of working with the Finder in Tiger. Previously, if you changed a file's extension, the Finder prompted for confirmation. But since no one has ever accidentally changed a filename extension, Apple thankfully added an option to turn that warning off in the Leopard Finder's preferences. Choose Finder > Preferences, and in the Advanced screen, deselect Show Warning Before Changing an Extension.
