amo开始检测可兼容5.0的扩展，并且自动升级。

Good news! Our automated tests did not detect any compatibility issues with your add-on XXXX and Firefox 5. We've updated your add-on's compatibility to work with Firefox 5.* so that our beta users can begin using your add-on. Firefox 5 beta was released earlier today.

话说5.0beta好像没什么实用的新功能啊

是的，官方校验目前4.0下面的扩展不会与5冲突，就自动将版本升级为可支持5.0的了。
