a) double check to make sure FF 2.0 can get through your firewall
b) double check that any virus scan software isn't blocking http traffic, and also that it isn't blocking FF2 specifically
c) In FF2, tools / options / advanced / network tab / settings button: look through that and make sure all is well. For starters, click the "Direct COnnection to Internet" to get it working & all checked out. If you want to put in proxy settings, save that for later on.
d)
See if this helps
e) be sure to put in the speed - up tweaks
there's a group of tweaks that'll speed it up a lot, but I don't have them handy for you. Google Firefox tweaks or you can also find them somewhere in this AT Software forum.
e1)here's just one of the several tweaks, you find the rest of them:
Speed up page rendering
By default, Firefox doesn't try to render a web page for 250 milliseconds while it's waiting for data. If you use about:config to add the Integer preference nglayout.initialpaint.delay, and set the value to 0, Firefox immediately starts to display the page, even without complete data.

1.Type "about:config" into the address bar and hit return.
Scroll down and look for the following entries:
network.http.pipelining
network.http.proxy.pipelining
network.http.pipelining.maxrequests
Normally the browser will make one request to a web page at a time. When you enable pipelining it will make several at once, which really speeds up page loading.
2. Alter the entries as follows:
Set "network.http.pipelining" to "true"
Set "network.http.proxy.pipelining" to "true"
Set "network.http.pipelining.maxrequests" to some number like 35.
This means it will make 35 requests at once.
3. Lastly right-click anywhere and select New-> Integer. Name it "nglayout.initialpaint.delay" and set its value to "0". This value is the amount of time the browser waits before it acts on information it receives. If you're using a broadband connection you'll load pages MUCH faster now!
there are additional speed-up tweaks you'll have to search out, I don;t have links to give you
look at the extension Fasterfox too (I don't have experience with it)
