Quit working AGAIN Rated 2 out of 5 stars
Once again, it is no longer working for non-gmail.com accounts. Last time it had this issue, it needed a hack to fix it. This plugin is no longer maintained by the author. I just found Gmail Manager NG, which is this plugin, but updated and maintained by someone else.
SKIP THIS ONE! Rated 2 out of 5 stars
1. This add-on has been ABANDONED by its author. It DOES NOT WORK as-is for gmail.com accounts. It is only working if you have a google apps account.
2. It should not be necessary to download a third-party HACK to get an add-on to work.
4. If you've never used this add-on before, don't bother. If you've been using this for awhile, it's time to look for something else. I only give it two stars because it hasn't broken for google apps accounts... YET.

It works if you have a Google Apps email account, but for gmail.com accounts it is BROKEN and it appears the developer is no longer maintaining this extension.
