Recently moved a website to a new server.
Updated the name server records in the Domain Registry account.

If I view said domain on any other computer or indeed any other BROWSER other than Firefox, they all point to the new server and the site loads up just fine.

BUT Firefox doesnt seem to recognize the DNS changes.
I guess Firefox must cache the DNS nameserver information somewhere.
Is there a Firefox Addon or some other way to flush this DNS information?

I'm using Windows 7 Ultimate btw.

Maybe this is the solution?

It's your computer or your router that caches DNS NOT the browsers.

Ctrl+F5 will force a browser cache flush and refresh on any particular page.

Flushing the PC cache is done from a command prompt. Start a Command window (cmd.exe) and type: ipconfig /flushdns <enter>

Some ISP routers are also DNS caching servers and a power cycle of one minute will ususally flush it.

Your ISP's DNS server may not have picked up the changes I bypass this by using Google's public DNS servers, the V4 IPs are:
8.8.8.8
&
8.8.4.4
Open the IP V4 TCP/IP properties of your NIC, select "Use the following DNS server addresses:" and type the numbers in

V6 |IPs are:
2001:4860:4860::8888
2001:4860:4860::8844
Same process here but select TCP/IP V6 properties.

Thanks Chris.

Seems very strange that Chrome points to the correct server BUT Firefox does not EVEN on may same computer.
That suggests to me that something is being cached at the browser level.

Anyway, the above Firefox Addon did the trick.

btw I use Ctrl+F5 all the time but I don't think it works for flushing the DNS cache.

Chrome does go into the network stack at a low level

gee , why didnt I think of that.

Just fyi

The people who develop these add-ons are geniuses in my opinion.
But sometimes the UI component or the way you are meant to get
the dang thing to work is very "non-genius".

In this case, once the "dns-flusher" add-on is installed (and you restart FFox of course) you should see an IP address in the bottom right corner of your browser. To FLUSH the dns cache you need to click on that IP address.
In the bottom left corner of your screen you should see some stuff happening as the browser fetches fresh details from that IP address.

Works like a charm, but if you didnt know those simple facts you might scratch your head and give up.
