Last month, I hinted that if a release candidate for Firefox 4 came out, I would be reviewing plug-ins on it. Well, the release candidate hasn’t come out, but I figured that a GeekDad reader like you might have his family on a beta browser release anyway. Is it practical? No. But what kind of geek would you be if your stuff didn’t break easily? So here you are: plug-ins for Firefox 4 Beta.
