Not rocket surgery but useful none the less, if you have upgraded to 64 bit or Ubuntu 10.x and found that you can no longer connect to your VMWare Server console in Firefox don’t get too bummed. The VMWare server will still let you install the plugin, it just will keep failing saying that the connection timed out…
So go ahead and install the console as usual and we will go ahead and call the vmware console extension directly and circumvent Firefox all together and avoid the issue 
It’s pretty easy the executable is located inside your firefox profile directory, you just need to mark it and a few supporting files executable so it will run and voila!
This an example from one of my boxes.
[code]
sgw@sobek:~$ chmod -R +x .mozilla/firefox/iez6qqlx.default/extensions/VMwareVMRC@vmware.com/
sgw@sobek:~$ .mozilla/firefox/iez6qqlx.default/extensions/VMwareVMRC@vmware.com/plugins/vmware-vmrc
[/code]
