Any program that is designed to prevent "pop-up" ads from appearing while you browse the internet can cause problems in My CCRI and Blackboard.

The reason for this is that many of these "pop-up" ads use the web programming language Java.

Thanks I am not that happy with giving too much right to Java Applets.

Also you should check /var/log/syslog for denied messages because Ubuntu has turned on extended dbus mediation and its denials do not go to the kernel ring buffer.

Also this profile should be reloaded to make sure the new rules are added.

I think I'll create a launchpad bug report against Apparmor, as this is in the default abstraction.

This paper will help you configure your web browser for safer internet surfing.

Some popular pop-up killers include: Another site that can help you recognize some of the current pop-up blockers if they exist on your computer and tell you where it is: a pop-up blocker software is installed, you must let it know that My CCRI is safe and that the windows can pop-up.

If you still cannot view certain My CCRI windows, turn the pop-up software off.

Whenever I try to run an applet, Firefox will freeze for some time.

It might be a long time, and I might have to kill Firefox. EDIT: I made sure apparmor is in complain mode, not enforce, for Firefox.

We suggest that you contact your company's IT department to determine if this is the case and ask if the port(s) can be unblocked.
