I am running Windows XP. I run Firefox 11.0, and I have Avast Free Antivirus Ver. 7.0.14267. When I open Firefox it always shows "cannot find server" screen. It cannot connect to internet. Multiple tries has no effect. I've done enough diagnosis to learn that Avast is what is stopping Firefox from connecting. Ive already checked the avast settings, and they're normal; nothing changed. But since I updated Firefox I can't get to internet. When I disable Avast, Firefox immediately goes to my home page every time- no problem! With Avast on , Firefox cannot connect to server! Are there any fixes for this? I like Avast and don't want to get rid of it, unless absolutely necessary. Can anyone help with this? I'd appreciate any help. Thanks!
