- Widget Style of GNOME/GTK Applications
it has no effect on the icons if you change it.
- 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.
- Configure web shortcuts
this should be turned off by default as (i think) it has only effect on konqueror
- Configure file associations
i think all should be turned off as it has no effect on TBB
I dont think we need cache as its disabled by default inside TBB
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.
