Impossible to show the list of category with Firefox

[ruera]

Alfresco ver: 2.9.0 B683
Foirefox ver: 3.0.5
Explorer ver: 7.0.5730.13

During the categorization of any document, wher i try to get the list, firefox diplays nothing. Whe I do the same operation with Explorer 7, the list is showed properly.
note: I' don't want to use Explorer…
Is there anyone who can help me to solve the problem?

Thanks in advance.

That was a bug with that version of V2.9. The workaround is to install Firebug into Firefox.
