[PC-BSD Testing] Firefox 3.0.4 repeatedly downloads but does not install

[Yvan Martin]

Launching PCBSD 7.01 AMD64 tonight, I am told of an available Firefox 
3.0.4 PBI Update. After two attempts at upgrading during which the 
process immediately says it has completed after the download is 
finished, I am prompted again for a PBI Upgrade.

I also tried downloading/saving  before running the PBI but the system 
says the archive fails internal data integrity check. I have never seen 
this kind of problem before and I have tried manually downloading from 
two different mirrors now with the same result.  Something is up.
