iPhones use the Safari Web browser to access the Internet. Safari on your iPhone has a group of standard settings that you can adjust, if you want. For example, you might want to take pains to protect your privacy and maintain your security.

Here's how to access Safari's settings:

  1. Tap the Settings icon on the Home page.

  2. In the Settings screen that appears, tap Safari.

    All Safari's settings appear for the changing.

Here are the Safari settings you can adjust on your iPhone:

  • Clear the history: To clear your history so that nobody else can trace your steps, tap Clear History.

  • Fill out forms with AutoFill: When AutoFill is turned on, Safari can automatically fill out Web forms by using your personal contact information, usernames, and passwords or information from other contacts in your address book.

  • Clear cookies: Cookies are tiny bits of information that a Web site places on the iPhone when you visit so that the site recognizes you when you return. You need not assume the worst: Most cookies are benign.

    If this concept wigs you out, you can take action in a number of ways:

    • Tap Clear Cookies at the bottom of the screen, and then tap it again (rather than tap Cancel).

    • Tap Accept Cookies, and then tap Never.

    A good middle ground is to accept cookies only from the sites you visit. To do so, tap From Visited. You can also tap Always to accept cookies from all sites.

  • Clear the cache: The cache stores content from some Web pages so that they load faster the next time you stop by. Tap Clear Cache, and then tap Clear Cache again on the next screen to (you guessed it) clear the cache.

  • Turn JavaScript on or off: Programmers use JavaScript to add various kinds of functionality to Web pages, such as displaying the date and time or changing images when you access them.

  • Fraud Warning: By turning this setting on, you'll be warned when you inadvertently visit a fraudulent Web site.

  • Block pop-ups: Pop-ups are those Web pages that show up whether you want them to or not. Often, they're annoying advertisements. But at some sites, you welcome the appearance of pop-ups, so remember to turn off blocking under such circumstances.

  • Databases: The database storage preference customizes how much space a Web app can have on your machine before it asks you for permission for more space. In most cases, you should just leave the default setting as-is and not give this another moment's thought.

  • Use Developer: Unless you happen to be a developer, don't pay much attention to this setting, either. It lets you turn on and off a debug console (showing errors, warnings, tips, logs, and similar details that developers find useful).
