Collapsible fieldsets empty - node settings, etc. unavailable! (Firefox 3) [#261250]

I have realized that some drop down menus (I don't know if that's the correct term) are not displayed. eg: when adding a node there are many options like "categories", "File attachments", "Format" "authoring"... and some of them are hidden by default and only their titles are displayed. Those titles are not always shown when using Fourseasons theme, as it can bee seen in the image below:

I can confirm this bug on Firefox 3 (works fine on MSIE 7 and Safari 3.2).

# Steps to reproduce #

1. Login as superuser (user 1)
2. Go to node/add/page (Create content > Page)
3. Click on 'Input format' or 'URL path settings' or 'Comment settings' or any of those collapsed fields

# Actual result #

The collapsed field expands slightly, with a grey border outline, but otherwise *no* options at all.

# Expected result #

Upon expanding, all options of the field set should be available, as normal.

I'm setting the priority of this bug to critical, since this bug makes it almost impossible to adminster your Drupal site...
