Please translate what the message says.

message? which message?

if you mean what this mozilla message says, here is the english translation (is this mozilla page the italian translation from english?):

Argh, this page is blocked! we can help you click the "restore" button to reload the page

In the grey box how send that page to support etc. (I did it but never got any answer)

Then 2 buttons: "close" and "restore"

The restore function restores the page but it crashes again and I cannot go back to the previous page therefore the session must be closed.

Reboot the computer.

Make sure you are not blocking content.

Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?
