Context: I’ve been using Network Monitor from the Developer Tools to save my requests in a .HAR file for further analysis via Right Click>Save All As Har
Case: When approaching around 300MB transferred, instead of exporting JSON formatted text into the .HAR file, it returns a 9 byte download and when opening the file it contains a string that says ‘undefined’.
Troubleshooting: I initially thought there might be a request limit, but when artificially inflating the request count past the initial amount of requests around the point of failure I did not experience the same issue - but did notice that the amount of data I was trying to save was considerably less.
Organically reaching the amount where things stop working I noticed it was around 300MB when I’d experience this issue. I was using an older version of firefox then updated to the most recent version to see if it was specific to that old version or a general issue, it was the latter.
I saw that when firefox saves logs per about:networking#logging
, it chooses the ~/appdata/ directory, and after looking through that, /appdata/local/Temp, and the Mozilla folder+subfolders in each /appdata/ directory I did not see a log that was relevant to the issue Network Monitor was having.

Question: Is this a bug, a known limitation, or does anyone know what is not defined upstream resulting in a ‘blank’ file? Is this something where I’d be able to look through a configuration file and set something in it to resolve this error when it happens? I haven’t found anything on this issue nor have I seen a data cap in the documentation.
