Having Problems loading Firefox

Well, I've decided to trash IE and replace it with Firefox. I followed the download instructions to the letter and when I went to open it I get this ALERT screen that tells me the following: "Start.Mozilla.org could not be found. Please check the name and try again."
What gives?? According to the stuff I've been reading it should take me to my Home page ... www.yahoo.com ... but it doesn't. It sits there like a lump. I'm certain I did something wrong and but I don't know what. Help!!

 

Make sure you are connected to the internet. Forwhatever reason, sometimes I get that and what I find, is that IE has changed from "always connect" to "do not connect" and that affects Firefox connecting. I change IE settings and everything works fine.
Also, like IE, if you want it to start on a particular homepage - you have to set it to do so. (click on tools).

 

Just to echo what BarnBurner said, once you get online, tools -> options -> general -> homepage can (just like Internet Explorer) set Yahoo as your default page. You have an internet connectivity issue which you know, but it sounds like Firefox installed just fine.

So now, let's figure how to get you back online, so you can start using Firefox (like Samuel Adams always a good decision). Are you using dialup? What happens when you try to dial out?
