When a javascript alertbox is opened in a site it is not possible to close the alertbox.

Chosen solution

Start Firefox in Troubleshoot Firefox issues using Safe Mode to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).

Can you close that box with the ESC key?

Don't you see an OK button?

The ESC key does close the box. I can see the OK button but it doesn't do anything. I noticed this weekend that this problem only seems to occur on a 32 bits Windows XP or Windows 7 and not on 64 bits versions of Windows

It was indeed caused by an custom Add-on. I notified the developer of this add-on. Thanks very much.
