I have upgraded my old version of firefox to Firefox 4 and when I try to open my webmail I get this message "Remote XUL, This page uses an unsupported technology that is no longer available by default in Firefox. Please contact the website owners to inform them of this problem".

Is there a fix for this as I cannot access my emails. My service provider is iinet.

This is an absolute disgrace. Mozilla have no right whatsovever to suddenly withdraw a working facility. The upgrade path should improve matters, NOT downgrade user's access to web mail. Who does Mozilla think it is - Microsoft ???

Just install this and add your website to the whitelist.

It has been disabled for security reasons.

They do have every right in the world. It's their software.
