You can launch chrome with google-chrome --app="http://app.com" And get a frameless window. Firefox used to have something like this, but it doesn't appear to work anymore. You can do firefox -chrome "file:///some/local/file.html" But obviously that's not quite the same, and I believe is limited to local files.
