   I was able to use SDM and ASDM with GNS3. I used IE and not firefox.

You have to enable http on the router and connect with SDM.

If it's not working, try to connect with IE.

   I have tested and it's working fine for me. I am using bridged connection between the cloud and the f0/0 of the router in GNS3. The interface works on internet explorer.

Here is the config and ios ver.
