Hello Sara.

Firefox 5 has not been released and there aren't even any plans for it yet. If you are using a browser that identifies itself as Firefox 5, it's a scam/malicious software.

You can get the latest official version of Firefox, for free, as always, at getfirefox.com.

As for your problem, if you are having trouble with an add-on, you will need to contact its author for support.

yeah you are right , mine is Mozilla 5 , Firefox 3.6.3

I downloaded Firefox from official sites

Do you have any idea about my problem ?!

As I said, you need to contact the author of the add-on. DAP is an add-on, right?
