Trouble with Prefbar install

I'm trying to install prefbar and have checked for web site to allow installation. It does not work. What is the address to allow for software install? Is it: Update.mozilla.org?
If not, please tell me what to put in for the allowable website.
Also tried to download file so I could install. Couldn't do that either.
Seem to be striking out today.
There is a very annoying Macromedia Bee add that has to be squashed by stopping flash. It makes this awful bee sound and will drive you crazy.
Thanks.
BTW, I am trying to do this install on Firefox1.0

 

I am a bit confused by what you are saying. This install and download confuses me. Anyway, I do my downloads from Extention room .
If you download the .xpi file or if you have it already, there is an easy way to do the job. I download to the desktop, and drag and drop the .xpi file into the the shortcut. It is more of a door knock, which alerts the program that something is needed, and the installation should begin, and complete.
I have had the Prefbar in 1.0, which I just upgraded to 1.01, and, it is, apparently compatible with it.
I find it more convenient to download the .xpi file, and save it for later use.

 

Thanks Westside for your comments. I went to the extension room and I do not see a place for downloading the msi file for installation. When I just clicked on the install now, it wants to install on my desktop, but when I wrote the note above I was on my laptop with firefox and I tried the install but it would not work. Where is the site for the msi download? I prefer to do it your way.

 

OK, I right clicked and saved the target so now I have the msi file. I have a quick start icon for Firefox in my taskbar tray. Do I simply drop the msi file on it and the install will start?

 

The file is .xpi, not .msi. As for how to do it, I would disable quick start, and use the desktop icon. I have never thought much of the Quick Start, or launch. In fact, I had no idea that there was one. Do you have a Desktop shortcut icon?

 

I have an icon on the desktop. If you want to have a quicklaunch, drag the icon to the quicklaunch area and it should be captured. That's how I got mine there. If you also want it on your desktop, you might want to create a copy before you drag one of them to the quicklaunch.
Anyway, I now have prefbar on the desktop and you say I should drag it and lay it on the desktop Firefox icon, right? Yes, it is xpi--sorry, bad eyesight or not careful looking.
