Is it possible to create a link to the browser's homepage ?
As far as I know, this isn't possible, and could be a security hazard.
IE used to have a internal about URI scheme that does that, "
about:home" which might still work in IE8.
I'd recommend not. Users know how to get to their browser's homepage. There's a perfectly good mechanism in place for getting there :)
Not sure what you're asking. You can create an HTML link like so (replacing the domain/title with the one you want:
<a href="http:/somedomain.com/" title="A browser to surf the web with">Browser</a>
If that's not what you're asking, please give a little more detail.
