I sent an Email to Liteon with regards to that issue, cause I don't like to be forced to use IE...
There is their answer:
[B]Dear Sir or Madam,
Could you please tell us the exact model name of this drive?
You could get it from the safety label on the top of the drive.
As regards LiteonIT products,we would suggest you use standard IE to download
the firmware from our web site.
If you have difficulty in the downloading,please free free to contact us,and we would
send the firmware to you.
Would any further information, please kindly visit LiteON IT Corp official web site -
If you reply do please include all previous emails.thank you very much!
Which means: You must use IE...
