I have recently posted a question because firefox would not open on my desk which uses XP and has version 3 on it. I have tried restarting, also looking at my firewall settings and turning it off and then on again but no luck. I could not start it in Safe Mode. So I uninstalled firefox and have tried to upload it again using Internet Explorer as my browser. However something is blocking it. Internet Explorer does not like the website and gives me unsafe messages. I have looked at the security settings and allowed Firefox although it seems to open as a http site without the 's' whereas my laptop using windows 7 has the 's'. I put in the 's' manually and it accepted it as a safe site but again blocked the download. Any suggestions gratefully accepted. I hate using Internet Explorer and have been using Firefox for years with not trouble until now.
