Thanx MrDave,
Q1: Ok, will delete from PROPERTIES on FIREFOX.
Q2, Q5: Was a mistake by me.
I ran v.7.2. but did not deleted TEMP from FIREFOX, so it was running 7.2 with some of 7.1 on cache.
Now I see the "SAVE DIR" label to write destiny folder, and also the iTunes drop menu at SETTINGS
Q3, Q4: Will wait... :)
