>>DevTools now shows server side events in the Network panel. This allows a server to send new data to a web page at any time allowing developers to see events they previously couldn't and help with lower-level troubleshooting. Would someone please shed more light on this? I work on BMC’s Remedy ecosystem and server side logging something that needs to be turned on separately. Does FF 82 help me capture it just like that or I need to do some configuration changes on the server? Pardon my simplistic question.

That looks to be a typo in the release notes. "Server sent events" is a specific server-> client HTTP communication mechanism. The Network DevTools already showed standard AJAX requests, and support for showing messages sent over websockets was recently added. This adds support for another mechanism that was not previously displayed: https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events/Using_server-sent_events https://developer.mozilla.org/en-US/docs/Web/API/Server-sent...

  That's good news. That was one of the things for which I had to switch to Chrome.

I too was interested by this. If you follow the links it's all documented: https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events https://developer.mozilla.org/en-US/docs/Web/API/Server-sent... https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events/Using_server-sent_events https://developer.mozilla.org/en-US/docs/Web/API/Server-sent... > Traditionally, a web page has to send a request to the server to receive new data; that is, the page requests data from the server. With server-sent events, it's possible for a server to send new data to a web page at any time, by pushing messages to the web page. These incoming messages can be treated as Events + data inside the web page. Push-based server->client messaging. Exciting stuff.

  How is this different from SSE or WebSockets?

    Isn't SSE the abbreviation for Server Sent Events?

    This is SSE. Here's a good answer on SO comparing the two: https://stackoverflow.com/a/5326159/1714997 https://stackoverflow.com/a/5326159/1714997
