Best iPhone, iPad Emulator - See How Your Website Looks In iPhone or iPad Using Only Your Browser

User Agent Switcher Add-On is a browser extension that lets you switch the user agent of a browser. Put simply, you’ll be able to view the iPhone, iPad or mobile version of any website in just a click. The extension is currently available for Firefox and will run on any platform that this browser supports including Windows, Mac OS X and Linux.

Here’s how you can preview your website in an iPhone or iPad using User Agent Switcher Add-On for Firefox:
  1. Download and install the user agent switcher add-on for Firefox. You may need to restart your Firefox for the changes to take effect.
  2. Download the following list of user agent strings for iPhone, iPad and various other mobile devices:
    These are XML documents which will let you change user agent in Firefox to the user agent of an iPhone, iPad, BlackBerry, Nokia, Samsung and other popular mobile phones.
  3. After you’ve downloaded the XML files, go to Tools > Default user agents and click on “Edit user agents”.
  4. A small window should popup where you can see an “Import” button. Now click on that button and import the XML list of user agents you just downloaded.
Once you have imported the lists, you’re now ready to test and preview your website in an iPad, iPhone, Android, BlackBerry, Nokia and other mobile operating systems. To start, just select the default user agent and select the device where you want to preview your site’s design, and reload the page.

Update: ScreenFly is an excellent emulator too. No more pesky-clicking involved.
