It happend some time ago once but it's happening again. Now it only works for IE. I always used FF and opera and it worked fine but lately FF can't view it ( look at the pic)..and in opera it loads up but i can't click on anything - i mean i can but there's no reaction - i loaded my laps by typing whole url clicked on pb to delete it = no reaction :/ - i can't move windows in it i can't do anything - what can be wrong..i'm 99% sure it's something with my browsers - i reinstalled them nothing has changed :/
I have formatted my hdd few weeks ago and it was again working fine..3 days later..again it's down in FF and today it went down in opera(like i said earlier) :/
Is there something i can do?
Sry if it's a repost but i didn't found similiar posts via search option.

It certainly has to do with your end I'm afraid.

I'm using IE & Firefox with no problem at all.

Tried and older version of Firefox maybe?
Use fresh copy of FF with no old profiles and/or extensions.
The fact that it worked for three days and after that doesn't really shows that something goes wrong with your computer as you use it.

Perhaps a virus, or firewall setting?

One thing you could do is download portable firefox http://portableapps.com/apps/internet/firefox_portable and try using that for lfsworld. This is completely isolated from your normal firefox installment. Don't change any settings on this one.
Just use it until it goes wrong. Maybe in the meantime you'll figure out what the problem is.

Well the ff i was using was 1.5 version. I doubt that i could have a virus that made this mess..i'm behind a router and have zone alarm too - they should be configured well as it just happened not instantly but after few days. I even turned off zone alarm nothing happend of course. Scanned my pc last night nothing was found by 2 antivir software.
Thanx for portable FF it's working just fine in there.
Once again thx for all tips KMSpeed

i have the EXACT same problem with Firefox (any version) - i've made my own copy of Portable just for LFSW to fix it

Well its obvious: If it worked for 3 days, and then it stopped working "all of a sudden". So what have you done after those 3 days? A system that is not modified always works the same way, even a Microsoft one. Well, mostly

If you Format C: and install only the required drivers and Firefox, lfsw will work for a hundred years.

What are those extensions you are using?

btw, zone alarm doesnt save you from virusses, it saves you from "hackers", which are blocked anyway if you are behind a router firewall...

I was using 2 extensions most of the time switchproxy and showip. Nothing was done after those 3 days..i just started my pc lunched ff and it was there. For now i cleared my opera dir completly installed it and it's working again...i'm gonna use this till it drop dead again and repeat the steps - and if it won't work i still have portable ff wich works fine too.
And yes i'm using antivirus soft all the time too..for home pc (router+zone+antivir) it's good enough i think.

You probably installed an ad blocking plugin that kicks out a certain java script needed by LFSW. At least that was the case when I had the same problem quite a while ago. I recommend using AdBlock as it doesn't break LFSW.

Try to disable all related extensions and see if it works again. If not, it might as well be a custom profile setting that got saved somewhere on your disk in the Mozilla profiles folder. You could try creating a new FF user profile and see if it works (which is very likely).

OR one of your AntiVirus/Firewall programs could be blocking that JS code.

Thx for all tips..i check them later as i don't have time for this now.

EDIT:
Well i'm using opera and ff 2.0 portable just fine now...old ff 1.5 is gone - i deleted it.
Case sold i think ..Thank you all for help.
