Do you reproduce the problem testing our online examples in Firefox 3? You can test whether you will reproduce the problem with the Commands
online example in which the OnClientCommand event is used. We tested the described scenario with dynamically created dock in Firefox 3 as well and were not to reproduce the problem you mention.
In case you are not able to reproduce the problem with our online example, please, open a support ticket and send us a simple test page which demonstrates the issue so that we can test it on our side and investigate the problem. Otherwise, if you reproduce the same problem on our online demos, the problem is most probably due to some FF configuration settings. You can check in the Firefox browser
Tools->Options->Content tab whether scripting is enabled.
Please, let us know how it goes.
All the best,
the Telerik team
