There are websites that won’t allow you to embed them inside your website. Google definitely doesn’t.
For example, this code will work just fine:
Me.LoadURL("https://example.org/")
It is up to the owner of the website to allow or prevent this behavior.
ok with example.org the first page is loaded the if you click on link more information the problem is the same of google.com
then i have tried with www.xojo.com and the problem is the same
It’s not an issue with Xojo. The site has a content security policy that blocks loading in <iframe>. There’s really nothing Xojo or you can do. If you control the server you wish to load a URL from, you can change those settings, but you can’t override the security of a third-party site. Typically, instead of loading such sites in an <iframe> or HTMLViewer, as we know it, the target page is launched in a new browser window/tab using the target="_blank" attribute of a link element.
ok in that case the HTLMviewer control is absolutely useless
For some sites, yes. This is, as I said, a security measure meant to protect people from being tricked in to providing their information – such as credit cards and login credentials – to a site that isn’t the intended recipient. For many other uses, the HTMLViewer is still very much useful.

Firfox gives good information about the why:
The HTMLViewer can’t break the security settings for a site, it is the same as if you have an .html file in your computer/server and you try to open an iframe to that site (as mentioned above), try this:
<html>
<head>
</head>
<body>
<div style="left: 40px; top: 20px; width: 532px; height: 300px; position: absolute;">
<iframe src="https://www.google.com" style="width: 100%; height: 100%;"></iframe>
</div>
</body>
</html>
you will get the exact same result.
