I know it's not exactly the use for a browser one could expect, but it would be useful it there was a way to explore the DOM of a page (read/set values) and send commands (clicks, for example) with automation, not manually.  

It could be with C, C#, even VBScript, for what I care, or DDE (but this seems to be a no), or using a third party extension... Anything could do.  

The fact is that this way could be difficult, but precise. I could use AutoIt, for example, but it would blindly execute the script without really having the possibility of managing problems.  

The browser has to be chrome. I don't have much hope, but I can still ask...

The obvious answer would be "make your own extension", but I'm trying to avoid that.

UPDATE  

The "headless browser" thing seems nice, but in effect I need to use the interface by hand before leaving it to the automation, it should remain visible.  

...Essentially because I need to activate an app, and I do it by hand, but I'm searching if there's another way.  

EDIT  

Yeah, it seems they are 'explorable' by url, so this shouldn't be a problem.
