Alright,
If you do have a dock do that if you don't and you just have a Dell just drag it to the main screen. I regret any confusion.
#6 already said it shows on the main screen = I'm guessing you mean desktop
Anyway, dragging from the 'download' area to the desktop does no good even on a Dell as you noted:
I forgot a step.
You drag it to the screen then double click. That should do it for dells.
Why just Dells? Why not Compaqs? HPs? Alienwares? any of the many others?
On the other hand:
Alright,
If you do have a dock do that
Once you save the download to your desktop you will have an installer waiting to be installed. How will dragging this to a dock install anything? If I drag an installer to my dock, all I do is create a shortcut to the installer on my desktop but it doesn't install it.
If I double click and install firefox, once it's installed I can't drag firefox to the dock because firefox is not on my desktop unless I told it to install there. Firefox is in a Mozilla folder in C:\Program Files. What I will have on the desktop after installing is an installer and maybe a desktop shortcut icon. Which were you suggesting to drag to the dock? I suggest the desktop shortcut.
boss was being sarcastic,
no way.
Bichur was just have a little fun at your expense, he already has Firefox installed and does use ObjectDock so does have a dock.

I forgot a step.
Actually more than one. Once you click download, every browser I have used gives 2 choices: download and run (or install) OR download and save. Your steps don't mention the choices.
Any instructional guide, even if only slightly technical, should include all steps and options within the steps.
the way I would and I think most would when go to download (in IE7, IE6 as no FF yet) is to select run on the download dialog so it downloads and installs without having to do anything else.
agreed. the trouble comes from 'most' doing that but not really being aware of from where they download. a better habit is to choose 'save' as the first option then scan the download for nasties before double clicking or unzipping or whatever.
