Blocking Pop-Ups
Many websites have pop-ups—new pages that appear when you didn’t intend for
them to. Many pop-ups are advertisements.
Block or allow pop-ups
m From the Home screen choose Settings > Safari, then turn Block Pop-ups on or off.
Blocking pop-ups stops only pop-ups that appear when you close a page or open a
page by typing its address. It doesn’t block pop-ups that open when you click a link.
Security Settings
By default, Safari is set to show some of the features of the web, like some movies,
animation, and web applications. You may wish to turn off some of these features to
help protect your privacy and iPhone from possible security risks on the Internet.
Change security settings
m From the Home screen choose Settings > Safari, then do one of the following:
 To enable or disable JavaScript, turn JavaScript on or off.
JavaScript lets web programmers control elements of the page—for example, a page
that uses JavaScript might display the current date and time or cause a linked page
to appear in a new pop-up page.
 To enable or disable plug-ins, turn Plug-ins on or off. Plug-ins allow Safari to display
some kinds of video.
 To set whether Safari accepts cookies, tap Accept Cookies and choose Never, “From
visited,” or Always.
A cookie is a piece of data that a website puts on iPhone so the website can
remember you when you visit again. That way, webpages can be customized for you
based on information you may have provided.
Some pages won’t work correctly unless iPhone is set to accept cookies.
 To clear all cookies from Safari, tap Clear Cookies.
 To clear the browser cache, tap Clear Cache.
The browser cache stores the content of pages so the pages open faster the next
time you visit them. If a page you open isn’t showing new content, clearing the
cache may help.
