If I enter any text in the alert dialog it is shown on the next alert - tried 10x in a row. What are you seeing happen?

When you click 'prompt' for the first time, everything is correct. The next window shows you the value returned by function prompt. But if you click 'prompt' for the second time (or more) and choose 'cancel' or just close prompt window, you will see 'works' instead of 'null' (you may compare the result in Chrome, for example)

I can enter text and click OK and I see the text. If I click on cancel the next dialog returns null.

Does the issue still occur if you start Firefox in Safe Mode? http://support.mozilla.com/en-US/kb/Safe+Mode

How about with a new, empty profile? http://support.mozilla.com/en-US/kb/Basic+Troubleshooting#Make_a_new_profile

Thanks a lot! I tested Firefox in Safe Mode and the problem didn't appear.
I found that the reason was the AlertStopper extension.
And yes, the second window returned the right value, but when I continued clicking 'prompt' it caused this mistake.
