I love firefox and use it all the time, so switching is fine. But this is actually just a simple settings issue.
1. Tools
2. Internet Options
3. Under Browsing History > Settings
4. Select "Check for newer versions of stored pages every time I visit the webpage".
There are a lot of nice features in firefox though. For example using the firebug plugin, I was able to figure out what code I needed from the chat page and the movie page (earl vs shane) so I could watch the movie and chat side-by-side. While surfing AZ, I can use the Stylish plugin to enlarge text boxes or the text, change the thread colors or layout, etc. It's really good stuff.
