Along with the customisable tab bar, Firefox 4 also looks set to gain a new add-on manager, which is currently receiving a major overhaul.
The new add-on manager works in a browser tab, removing the need for a separate window completely. Along with the standard options for managing extensions, themes, and plugins is the ability to manage both installed languages and search engines.
Currently it is still very much a work in progress, with not all functions working as intended, with icons and the interface still not final. Other features are still yet to be included, such as silent extension updates.
The new add-on manager is expected to start appearing in nightly builds of Firefox 4 soon.

The new add-on manager is already appearing in the nightly builds of Firefox 3.7. There are no builds of Firefox 4 yet, because it hasn’t been decided if firefox.next will be 3.7 or 4.0.

Which nightly build are you using? The latest Minefield/3.7a5pre build from 3rd May does not include the new add-on manager. Perhaps I am looking in the wrong place?
I do really need to get into the habit of calling it Firefox.Next too, as you are correct a final version number has not been decided on. I would be quite surprised if they did choose 3.7 instead of 4, simply because of the large number of changes from Firefox 3.6 (most of which appear more cosmetic).
