Is it possible to retrieve a user's homepage URL from the browser with JavaScript?

Question

Just so it's clear: I don't want to reset their homepage. I just want to pull the URL of their homepage and load content from it as part of an application demo.

So far my research hasn't turned up anything, is retrieving a user's homepage possible with JavaScript?

Answer 1

No, that would be a significant privacy violation. If browsers allowed you to access this data, you could potentially detect the user's e-mail provider, bank of choice, or company intranet if they had it set as their home page.

Answer 2

Not that I know of.

That'd be a pretty major security hole if you could.

Answer 3

No. That would be a horrendous security problem. I don't want AN Other web developer finding out arbitrary browser settings. That's private, and browsers correctly respect that.

Answer 4

如果它确实那么浏览器制造商需要与它的开发人员说一句话。
