As you know, all child windows/controls (ie. edit boxes, buttons, etc.) are windows, therefore you can get a HWND handle on them.

What about browser controls? I used Window Hack as well as calling EnumChildWindows() myself, apparently the screen that displays the web page is just one big window. What about all the controls inside? (ie. buttons, text boxes, text areas, radio controls, etc.) Are they windows as well?

I pretty much need to get a handle on a browser control in any browser, whether it be Internet Explorer, Mozilla Firefox, Google Chrome, etc. Any ideas?

Different browsers are going to implement these in different ways. I would check out the Firefox GUI library to see how it handles everything.

Note: you are assuming a Windows environment/methodology.

I think you need to call EnumChildWindows() on that big window as well, as I would think it's just a container. So you'll have to call it twice--once to get the container, and a second time to get the children inside the container.

If you look at the source code for Firefox, under the widgets/src/windows directory, you'll see that no controls are created using any variant of Win32 CreateWindow. I suspect these controls are being drawn and handled with a custom library which means they won't have hWnds. I'll have to look at the code further.

However, I did find that Firefox is compatible with something called the "Microsoft Active Accessibility API", but I can't post the link since I don't have enough posts yet. Search for "firefox accessibility api" on Google.

No, these are not windows at all.
You must use COM or ACC
For example, it's very classic to get them from IE with Win32 COM

Google Chrome runs on several operating systems, so it depends on which one you're talking about.
