SSE is a simple and straight-forward alternative to WebSockets when you need a one-way channel for events coming from the server.
In Chrome Dev Tools' Network tab, you can click the resource (url) where the SSE originates from and view the stream in a tab of its own. I cannot seem to find this functionality in Firefox.
Is there a simple way of viewing server-sent events in Firefox, that doesn't require me to change the source code (inserting logging statements)?
