Identity Chooser - a great choice Rated 5 out of 5 stars
This is an excellent add-on! You can choose from all of your identities when you compose, reply, and/or forward. It also will check to make sure you want to use the current id when you send. Setting different colors for each makes your identities easily distinguishable from each other so you are less likely to make errors. Also, I contacted the developer with a small bug and he worked with me to get it fixed in a few days. It doesn't get better than this! --SLSThis review is for a previous version of the add-on (1.5.3).
