I just got the latest build of Bon Echo, the alpha build of Firefox 2.0, and noticed a nice new feature called the ‘Addons Manager’. For what I can tell, it is a combination of the theme manager and the extension manager from previous versions of Firefox. I imagine that this could be expanded to include things just as the Flash plugin, Java plugin, etc. This is all a part of the visual refresh that is planned for Firefox 2.0. Here’s a screenshot:
The nicest thing about it is that there is now an options button associated with the extension, instead of down below. People always seemed to miss it before, so now it’s a bit more obvious.
