Hi Robert,

I'm sorry, it was my fault. The access was routed through a faulty proxy server. After entering the ip address of my Ubuntu machine into the proxy bypass list of FireFox/ Windows everyhing is working fine.

Hi Robert,

the problem seems to be very strange.

As I already reported I am using FireFox 10 on Windows 7/ 64 bit to access my Ubuntu machine running apache2 + mod_mono.

FireFox/ Ubuntu works without flaws whereas FireFox/ Windows 7 does not. In the next step I compared the generated
page source between the two test environments and realized that they are exactly the same!

The .aspx page loads 2 scripts starting with WebResouce.axd. When I click on such a link in FireFox/ Windows an empty page
is displayed. After clicking on View>Reload the script is finally displayed as expected. I have done these steps for both scripts.
If I then press F5 to reload my .aspx page, the menu bar is responding to mousover/mousout events but it still
shows the skip links.

I guess that something is wrong with mod_mono as well.

Hi Robert,

thanks for you explanation.

I checked the browscaps.ini in Mono 2.10.8. It does not support FireFox 4.0 or higher and FireFox running on Vista or 7 is also not supported. Furthermore, I can't see an entry with Ubuntu as the OS. This browscaps.ini file is totally outdated. It's unbelievable that the most widely used browser is not correctly detected by the current release version of Mono.

I updated my browscaps.ini file directly via garykeith.com. However, FireFox is still showing the described problems.
