Note that some CSS properties now longer need or can be prefixed with a -moz- prefix.
A good place to ask advice about web development is at the mozillaZine "Web Development/Standards Evangelism" forum.
The helpers at that forum are more knowledgeable about web development issues.
You need to register at the mozillaZine forum site in order to post at that forum.
Note that new members first post requires post approval to be seen by public. So be patient if it does not show up right away. This is due to the spam attempts that mozillaZine gets each day.
