'Block Site' merely blocks access to a list of sites, but does not stop them appearing. is there a way to stop websites which use <gob.mx> in the address, which attempt to re-direct to 'mirror' sites that try to steal personal info and generate 'Illegal re-direct' warnings from anti-virus programs from appearing in firefox searches, automatically, rather than having to enter <XXXXXXX, -gob.mx> each time I search ?
