I've got a user who reported that the menu does not render in Firefox on either Fedora 7 or CentOS 5.2.  All he gets is the Home item, none of the rest of the menu. 

I'm running a standard DNN V4.9 installation with the stock DNN blue skins. Site works fine on Windows client with all browsers I've checked (IE, FF, Netscape, Opera, Safari, Chrome).  I've confirmed the behavior using Firefox 3 under CentOS 5.2 running in a VM.

Where to start looking?  I'm guessing it's a javascript issue on the client??  Can anyone shed any light on this? 

Thanks,

Marty

I've mentioned this issue somewhere before.

My company admin's PCs are all on Latest Ubuntu+FireFox. Sometimes the menu just won't shown or just shown once.

Btw, did anyone notice that [LinkActions] cannot work on DNN 4.9? The Action button will show but nothing when you click on it.
I've tested in 3 DNN 4.9 Websites.

Here's what I've tested so far:

 Note that Firefox 3.0.1 was working on Ubuntu 8.04 until I updated it!  Yet, FF 2 versions don't work either.

I've also noticed that where this fails, the menu bar has a lighter colored rectangle containing the Home entry, overlying the gradient bar and stretching across the with of the bar up to where the search radio buttons start. 

Still searching for answers...
