Installing Firefox

I have tried putting together the steps necessary to install Firefox 
into this cmd file in the hope that someone might be able to point out 
where I have gone wrong.

This basically retrieves and extracts all the required archives, (unless 
there are more that I'm not aware of...)

Some variables are set and then firefox is launched...

At least in theory... firefox does do something, I'm not entirely sure 
what, for around a minute, but nothing appears on screen. Is there 
anything like 'verbose' flag I can start it with to see what it is doing?
