问题 I am trying to upload a video to Vimeo via Ajax but I am running into CORS problems with Firefox. Here is the code I am using. It is only at the last stage of posting the file does CORS protection prevent the upload. I have checked the headers and Cross Origin is set correctly. $.ajax({ url:'https://api.vimeo.com/me', crossDomain:true, headers:{Authorization: 'bearer ',Accept:'application/vnd.vimeo.*+json;version=3.2'}, error:function(){ videoError('Couldn\'t get a quota'); }, success
