Answer 1

That is a browser thing to help users get rid of annoying sites. If you click on that, alert s will still be fired, but you won't see them (which is not what you need if you are the developer).

Answer 2

The following steps show you how disable this Firefox feature:

1. Start Firefox, and type about:config in the url bar. Firefox will show the preferences screen. Please take care not to make changes at random.

2. Right click in the preferences area, and choose New > Integer from the popup menu.

3. In the dialog box that now appears, enter dom.successive_dialog_time_limit, followed by the value 0 (zero). Press OK.

When you return to the Promasys WebCRF, this message will no longer appear when opening the same dialog box more than once.

Answer 3

This alert has nothing to do with your code (apart from the fact that your alert calls triggered it), it's functionality found in some browsers to prevent "run-away" alerts (because they're modal).
