Logging Adsense clicks on Firefox

had anyone solved the onfocus problem?

I read a few threads about logging Adsense clicks.
[webmasterworld.com...]
[webmasterworld.com...]

I worked hard on testing them but none of the above worked for me on Firefox.
It is quite clear that it is not possible to catch IFRAME onfucos events on Firefox.
It is also clear that this problem has a solution.
Does anyone have a script that works on Firefox or knows how to solve this problem?

It is also clear that this problem has a solution.

is there a reason you are so confident that there is a solution to this? i would also love a solution, but i am not sure if it can be done reliably.
