Applications Style
- Widget Style of GNOME/GTK Applications
it has no effect on the icons if you change it.
Desktop Behavior
- Screen Locking Timeouts
it should be tuned off as it has no effect (or actually bad one) on a VM distro, since the host is the real distro who should use that.
Shortcuts
- Configure web shortcuts
this should be turned off by default as (i think) it has only effect on konqueror
Applications
- Configure file associations
i think all should be turned off as it has no effect on TBB
Settings
- Cache
I dont think we need cache as its disabled by default inside TBB
- Cookies
cookies inside TBB accepted only if TBB is opened but not offline or for future use. so cookies preferences should be changed.
- Browser Identification
This has no relation/effect on TBB, and if there is then its a bad one.
