Hi all, A few days ago I noticed that for some reason in my GMail account, I can longer Compose New or Reply to an email. Please see attached screenshot: http://chrisbartlett.net/Screenshot.jpg Any time I click either Compose or Reply, the "Loading" appears and just sits there forever. Nothing is freezing, and I can can navigate through labels, new tabs, etc... I simply cannot reply or compose. I also noted that "Reply To All" is no longer available. This is all only happening on one of my machines (this one). Other PCs remain fine. Help? Thanks! Using FF 21 on Windows 7 Pro x64.
