Every time I try to open the page 'http://localhost' in my FF, all I get is a blank, white page. I tried this with two different local server programs XAMPP and WAMPServer. Both give the same result, a blank, white page. Apache and MySQL, which those local servers provide, work perfectly fine. I can access that page only if I type in 'https://localhost' or the IP '127.0.0.1'. But IE, Opera and Chrome have no problem showing the page the normal way. Could you please tell me what my problem is? I tried to find something in other forums and asked as well in a forum for XAMPP? But they couldn't help me. I changed my hosts file and also tried to disable IPv6 but that didn't help. The servers are both working perfectly fine, there were no error messages when I installed them. I also tried to disable the firewall and see if that would be the mistake but that didn't help either. Here maybe some information you would need to analyse the problem: I use WIN7 Home Premium 64 bit, XAMPP version 1.7.3 and Firefox version 3.6.10 Thank you very much for all your efforts Jonny
