EventSource behaving differently in Firefox

I have an application which uses EventSource to capture the events from Server Side. I am using Angular as my front end, From the documentation I understood that EventSource will automatically try reconnecting if there is any issue with the connection, like when I stop the server I could see that chrome is trying to reconnect the connection. But in Firefox that connection is lost and it is not retrying, is there any work around I need to do for Firefox?
