Will some websites not open in Safari for Windows, claiming they must be opened in either Mozilla Firefox or Internet Explorer? Are you developing a website and want to test to ensure the stylesheet changes correctly based on the browser? Or are you just curious if webpage content changes depending on the browser accessing the site?

For these and other reasons you can fake Safari's user agent string so that when you visit websites they think you are using Mobile Safari for the iPhone, Internet Explorer, Opera, or any other browser if you know its User-Agent string.

First you must open the "Develop" menu in the Menu Bar if it is not already present:

1. Press the general Safari settings menu button near the top-right of the browser (it looks like a gear).

2. Select "Preferences" from the pop-up menu.

Or, press Ctrl + , to open the Preferences window.


3. The "Preferences" window appears. Select "Advanced".


4. Check "Show Develop menu in menu bar".


5. Click the "X" at the top-right of the "Preferences" window to close it.



Now to fake your User-Agent string:

1. Press the Alt key to open the Menu Bar if it is not already open.

2. Select the "Develop" menu.

3. Click "User Agent".

4. Select a User Agent from those provided, or click the "Other" option to enter a custom user agent string.

Your user agent should remain in effect for all pages browsed with the current tab.
