Status: RESOLVED DUPLICATE of bug 1223726

(DevTools :: Netmonitor, defect)

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:59.0) Gecko/20100101 Firefox/59.0
Build ID: 20180122144853

Steps to reproduce:

I opened Network Tab of DevTools and was checking the response of an API in a web page for work. 


Actual results:

The actual response size was ~2.80 MB but when I try checking the response or copying it through right-click context menu, it seems that Firefox clips it at 1048576 bytes (1024 * 1024 bytes or 1 MiB). Is this a known issue?


Expected results:

The entire response should have appeared in the response tab, and also copying the response using the right-click context menu should copy the entire response.

Attachment: The API call in question with a 2.80 MB JSON response.

Attachment: Response tab for that request. The response is clipped at exactly 1 MiB and hence Firefox fails to parse the JSON.
