rosweb for firefox

[matzeHN]

I would like to use rosweb with firefox, but evertime i try to open a widget i get the following error in the firefox console: "No unique Widget found with id equals to Nan on the list above" see pic. attached. The connection to rosbridge is working well. If i try to open a widget on the same machine but with google chrome browser, there are no problems.
