i dont mean it should be done automatically ,
In Internet Explorer 7 and earlier it was possible to do this using
However, this is not possible in more recent version (as it is considered a security risk) and has never been possible in other browsers like Firefox.
The best fallback is to actually instruct the user how to change home page instead of programatically trying to accomplish it.
In Firefox (I'm not sure about other browsers) it is possible for the user to drag a link and drop it on the home button, and thereby (after confirming) changing the start page. You may utilize this by instructing the user to drag an image (that is inside an anchor tag linking to your website) and drop it on the home button.
This isn't possible. That would be a security risk.
You can't. Not since IE7.
<!--[if IE]> Click on the "down" arrow just to the right of the "house" icon in your Internet Explorer toolbar and choose "Add or Change Home Page." Then click on "Use this webpage as your only home page" or "Add this webpage to your home page tabs," depending on your preference. <![endif]--> <![if !IE]> To make this page your home page, just drag the icon to the left of the URL in your location bar onto the "Home" icon in the "house" icon in your toolbar. Some browsers do this differently. You can always set your home page through the preferences of your browser. <![endif]>
