After installing 2.4.1 I've notices that the page editor refused to load completely. TinyMCE doesn't complete and the entire CMS just hangs. It works fine in IE8 but not in FF. When the CMS first loads the first page that loads up is fine, the editor loads properly and everything, but once you try and navigate to a different page in the site it borks. I'm attaching a video here to show what I'm talking about.

Chrome and FF respond the same, IE8 seems to stumble then pick up fine
