I've just installed CrunchBang and I'm exploring the default Firefox front end called Iceweasel.
However, the UI of it seems to be tweaked to be Windows-friendly. Instead of the familiar "File Edit etc" menu bar at the top, there's only a single "Iceweasel" button, like with Firefox on Windows.
I'm pretty sure that there are written rules on how UI layout should be set up on GNU+Linux systems and I'm also pretty sure this is breaking them.
When I used vanilla Debian the Iceweasel UI layout was set properly, so there has to be an option.
