Broken

Same happens to me with many different themes I tried (know and well written ones, like twenty ten/eleven/twelve and thematic framework). I also have the latest jquery linked in my header. No Javascript errors were found in the FF console neither. I also would appreciate any kind of help.

If somebody faces the same problem, here is how I managed to fix it: looks like the google analytics .js (asynchronous version) broke a variety of my plugins, not only the front end editor one. Although it’s recommended to have the analytics .js in the top of the document, you should keep it declared under all other scripts you are using. After doing that all my code run again.
