There's a neat program called wmctrl
that allows controlling window properties, including titles.
For instance, run this in terminal:
while [ 1 ]; do wmctrl -r :ACTIVE: -T " " ; done
This will set whatever your active window is to the text you specify with -T flag. Thus, any active window, once you bring it up, will get set to blank title. So all you have to do is bring up the application, and there you have it !
You can put that into a script, and make that script a startup application. For more info on how to achieve that, read here
Note, wmctrl
isn't default package. you have to install it with sudo apt-get install wmctrl
The title bar in chrome (or any browser) is typically set by the webpage. Your going to have a very hard time overriding that.
If you switch to gnome 3 there are ways to fool the system into displaying an empty title bar. There is no way to do this in unity that I am aware of, and no way to do it application specific without removing window decorations. If your willing to remove window decorations then you can try Maximus for gnome 3 or develspie. There are other programs and scripts that will let you modify window proprieties. The one your looking for is "undecorate".
You could of course compile your own window manager and just change the parts that display the window title. However that's pretty advanced. If your just trying to stop prying eyes you could write a quick chromium extension that sets a title to "".
