Dragama, could you help here like in bug https://bugzilla.mozilla.org/show_bug.cgi?id=1337826#c6

This crash in the pipeline feature. This feature is disabled by default on Firefox Desktop for very long time. Can you disable it for your users?

(The pipelining is completely removed in Firefox 54)

Thanks. That is really old strings in config :) Commented. Testing.

//defaultPref("network.http.pipelining", true);
//defaultPref("network.http.pipelining.ssl", true);
//defaultPref("network.http.proxy.pipelining",true);

Could it be source of strange network freezes? ~ every 30min in 52.1.x

Not that I know.
Can you reproduce it? You could make a http log and I can take a look:
https://developer.mozilla.org/en-US/docs/Mozilla/Debugging/HTTP_logging

you can limit the size of the log and the log will be rewritten, so as soon as you notice the network freezing please close the browser so that the relevant part of the log is still in the file.
