I am not sure if I am the only one with this problem, but sometimes FireFox freezes for a second and than gives me a warning box about a blocking script

It happens not always, but if, than it happens on every page load where FireFox freezes for some seconds and shows me that box.

Is there any solution for it?

Also it happens relatively often, that the forum does not load at all giving a custom screen with "not available".
