[G4] Firefox dmg install?

[Fast Primes]

Hi Folks,

In attempting to install Firefox, I found myself having to re-install it all 
the time. Here's what I do:

    -   click on the firefox--xyz.dmg file
    -   the system works on this a few seconds
    -   then it presents me with a screen with the Firefox icon,
        a pointing arrow, and the Applications folder icon
    -   clicking on the Firefox icon in the above box installs Firefox
        in the dock with it bouncing a bit (until complete?)

However, on powering up, Firefox is NOT in the dock (nor in the Applications 
folder)--neccessitating that I repeat the above steps! What am I doing wrong 
here?

Thanks.

FP
