If the CSS-Selector -moz-system-metric(touch-enabled) reports true, the tab bar looks ugly.
- The bar itself will be too tall
- The close button of the tabs is scaled to a pile of pixel clutter

Reproducible: Always

Steps to Reproduce:
1. Use a touch enabled computer and start Firefox
Actual Results:  
See Details.

Expected Results:  
I personally would like the tab bar to be the same as when no touch is available. At least the design should be pretty and not such a clumsy trial.

-moz-system-metric(touch-enabled) reports wrong. I use a Dell XT2 Tablet and have the touch input disabled (Control Panel, Pen and Touch, Touch, "Use your finger as an input device" unchecked), so only the pen can be used.
Second the property should be monitor-dependent. Only the laptops integrated monitor is touch/pen capable, not an external monitor.

Yes, the property should be monitor-dependent. I took a look at the win32 docs but could not find any references on how to retrieve information for specific monitors (the docs seems to all be system-wide).   I don't have a multiple monitor setup at the moment, so could you test if you set Firefox to open directly on the external monitor the results are the same or different?

I think that the bigger targets have a value even if using a pen, but I agree that some users might be uncomfortable with the changes, so maybe having a setting to disable this would be reasonable.

I don't know the Windows Touch/TabletPC API well enough to say "use this api", but the Managed Code property Tablet.TabletDevices might be a start:

Currently it doesn't matter on which screen I open Firefox, it always show the scaled buttons. Even if the laptops internal monitor is disabled.

I personally don't see any advantage of bigger buttons for pen input as the pen is very precise. An option would be a good thing here.

Larger icons for touch input is a great idea, but this isn't complete by just increasing the height of the tabbar by some pixels. This affects the whole browser: Menubar, Option Dialogs, Address-Bar, etc.
