Sorry. That's what it shows after disappearing. Here's the orig. link:

Well it hasn't happened again yet, but could you explain the logic behind this and the significance of the DNS server.
My iMac uses a wireless router. The DNS server says 192.168.1.1 but this doesn't seem to be open to change. (The iMac doesn't show any such problem anyway).

A DNS server translates a domain name such as meon.zero.eu.org to an IP address such as 188.8.131.52
This is equivalent to translating: Natural History Museum, Cromwell Road, London to SW7 5BD
National Institutes of Health, 9000 Rockville Pike, Bethesda, Maryland to 20892
Unfortunately some people have preferences with DNS servers which invoke advertisements. These could be caused by a virus or by somebody supplying modem/routers with them. Several web pages claim that one of the UK's largest ISPs did this.
The simple fix is to use the DNS server I gave you.
Many modem/routers are located at 192.168.1.1
All addresses starting 192.168 are on your private LAN.
You could access your router and change its DNS server address which it passes on as the default to computers connected to it.

Firefox 3.6.28 is long outdated and no longer secure. You can not run the new versin of Firefox on your Mac. Your best option is to get TenFourFox, which will continue the security patches needed, but allow you to run it on your machine. Plugins like Java and Flash are disabled by default because they are not secure. You can renable the Flash plug-in -- but be careful to use it selectively only; it is very outdated. Get the FlashBlock add-on, which won't load until you click a placeholder.
To reenable plug-ins (but DO NOT reenable Java -- big security risk.)
I doubt this is a DNS problem, but I would recommend DNS from OpenDNS. Those servers are patched against DNS poisoning.
You don't need to go to the OpenDNS site to use OpenDNS. Simply open Network>Advanced>DNS in Sys Prefs and enter the following numbers for the interface you use, e.g. Airport or Ethernet,
Hit OK and then Apply. Make sure those numbers are entered above any others you may have there.
To check to see if it's working
Thank you. Oh dear! Do I really want to start with a new untried browser? I'm inclined to give in to the 'blackmail' and on the G4 switch to Safari, keeping Firefox on my iMac where I can perhaps naively hope that it will be updated and protected. And do you really think I should
move to OpenDNS?
Why is life so bally complicated sometimes?

You really have nothing to lose -- well, actually a lot to lose if you don't stop using the unsafe 3.6.28 -- and everything to gain by switching to TenFourFox. Safari for Leopard is not secure; it's no longer being updated by Apple. Likewise, your old version of Firefox is no longer being supported by Mozilla and is unsafe.
It's not really a "new" browser. It's really a modification of Firefox. You just get the Application and it will use the old Firefox Profile. You can continue to use Firefox Add-ons and everything else Firefox.
I don't know what iMac you have, but if it's not an Intel iMac, you're still stuck in the same situation there.
If you want to continue to be safe, you really have no choice.

My iMac is the 21.5" Intel 500GB model running Snow Leopard (so that I can Rosetta AW).
There, you can easily update to the latest Firefox 14.01. Or the 10.05 (or 6?) ESR
Disregard what they say about it not being meant for individuals. You can use it. It will include the most important security patches. But you'll be fine with the 14.01.
