I used etax 2013 worked ok...then when ,my guard was down....used it again for another family member.
Etax2013 buggered up the password (right at the end of the tax entries) then wouldn't let me re-enter data to get a new password, it locked out half the keyboard keys. A first I thought the KB had died...many KBs later no fix.
Called the eTax help line...they said I had to clear firefox cache...what a joke...I asked if they were serious ...unfortunately they were!

(for the uninitiated etax program had nothing to do with firefox, completely separate programs and firefox was not running). The help desk had no idea at all!
Took me 3 computers and a number of uninstalls and re-installs and fresh downloads to finally fix it.
Then used it again a few days later for another family member...wet thru all ok. So go figure!
