Stop Firefox from displaying the message "Prevent FireFox from displaying additional dialogs"

Question

I have a portal site for employees. At a certain time, the script can display two warning messages in a line. When this happens, FireFox offers the user the ability to prevent the creation of additional dialogs. When a user checks this field, none of the following alerts will be displayed during this session. In most cases, this is an undesirable behavior.

If you have control over user browsers, as is the case with the internal program, see my answer below, how you can disable this feature:

Answer 1

1. Copy this string to your clipboard: dom.successive_dialog_time_limit 2. In FireFox Address bar Enter: about:config and press enter. 3. Accept the warning dialog. 4. In the preferences area right-click. 5. Select New-> Integer 6. Paste the string you copied previous and click OK 7. Enter the interger 0 in the next dialog box and click OK. 8. Close the about:config page.
