One of the best things about ElasticFox is that you can add "Tags" to instances, EBS volumes, etc. Tags are your own notes about the instance, like a friendly name. I really wish Amazon had a field like this that was tied to the instance so it would be available in all tools. One minor draw-back to tags are that they only apply to the particular browser in which they are created. They don't, for example, if you logon as a different user to your machine, or on other machines.
With ElasticFox you can connect to various regions, even with different credentials. It allows you to manage the following by selecting the appropriate tab:
- Security Groups
- Elastic IPs
- Volumes and Snapshots
- Bundle Tasks
- Reserved Instances
- Virtual Private Clouds
- VPN Connections
- Availability Zones

ElasticFox doesn't support versions of FireFox above 3.x, so get Elasticfox (for EC2 Tag) which adds a few more nice features.
