I found multiple pages recently that cause problems with the network monitor in firefox developer tools. I attached an image as an example:
The three requests are selected always as a “block”. They seem to be somehow related but I do not find any documentation what their relation is. My educated guess (also see http - What is the reason firefox combines multiple requests in the network monitor - Super User) that it is HTTP/2 related. However I still do not get how to handle debugging in such circumstances. I’d like to see the individual requests and answers for debugging purposes. I do not find a way to reach that goal. Is it a technical restriction?
I already asked this question on the user forum of Mozilla. Just for cross-reference.
