more options

I had internet explorer and it kept not responding everything. So, I recently downloaded firefox about 3 weeks ago and have had no trouble. I upgraded the updated version and now I am getting not responding again. Can you tell me what is wrong and how to fix it or can you tell me how to get the old version back. I do not have internet explorer on my computer at all anymore so if I delete it I am not sure if I will be able to get back on the internet. Please help

This happened

Just once or twice

== Today when I downloaded the updated version and 24/7 with internet explorer

You data indicates that you are using Firefox 3.6.4, which is currently in the testing stage. Try installing the latest end-user version from http://getfirefox.com

My guess is that you have a firewall of something getting in the way. See Fix problems connecting to websites after updating Firefox
