Are you sure that this is not a problem with JavaScript?

To avoid confusion:

You can try these steps in case of issues with web pages:

Reload web page(s) and bypass the cache to refresh possibly outdated or corrupted files.

• Hold down the Shift key and left-click the Reload button
• Press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
• Press "Command + Shift + R" (Mac)

Clear the cache and cookies only from websites that cause problems.

"Clear the Cache":

• Firefox/Tools > Options > Advanced > Network > Cached Web Content: "Clear Now"

"Remove Cookies" from sites causing problems:

• Firefox/Tools > Options > Privacy > Cookies: "Show Cookies"

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

• Do NOT click the Reset button on the Safe Mode start window.

This pops out when I reload that page...

Yew that is the Java Console that opens.

There has been a change in the Java security settings, see:

• http://kb.mozillazine.org/Java#Java_security_prompts

• "What should I do when I see a security prompt from Java?":

A possible workaround is to add the URL to the Java Exceptions Site List, see:

• "Why are Java applications blocked by your security settings?":
  http://www.java.com/en/download/help/java_blocked.xml

Thank you!
