I need to get a log of all files retrieved from the Internet when I load a page in Firefox; I cannot really use the Firefox Web Developer (Tools) / Network Monitor because some pages which use Flash, tend to crash Firefox for me when I have the Network Monitor open (even if they seemingly load properly without Network monitor). So I need to obtain a list of URLs that will "survive" such crashes.

I am aware that I can get a log of network traffic from Firefox by using environment variables, for instance on Linux (this works on Firefox 43, but I couldn't get it to work with MOZ_LOG_MODULES/MOZ_LOG_FILE):

NSPR_LOG_MODULES=timestamp,nsHttp:3,sync NSPR_LOG_FILE=/tmp/ff.log /path/to/firefox/firefox

However, this prints very verbose information with full HTTP requests/responses, like:

... and I really only need the full URLs, something like the lists shown by Firefox' Network Monitor:

enter image description here

So is there a way to persuade Firefox to dump only the accessed URLs in realtime to stdout or to a file, such that if Firefox crashes, I still have a log of accessed URLs?

I need to obtain a list of URLs that will "survive" such crashes.

The HTTP Request Logger Firefox add-on would appear to meet your exact needs:

Logs HTTP requests (referrer, HTTP method and URL) to a text file for security and auditing reasons.

Source HTTP Request Logger

Sometimes it might be useful to log each and every URL that is accessed through your Mozilla Firefox web browser. It might be for security, auditing or other reasons that you want to log accessed URLs. I developed the HTTP Request Logger add-on in order to track and discover a malicious web page that triggered the CVE-2010-4452 vulnerability in Oracle Java through a specially crafted applet tag and a respective Java applet class. You can download and install the add-on from here: HTTP Request Logger. You can also view the project on GitHub: prekageo/http-request-logger.

The add-on implements a JavaScript XPCOM component. This component is registered in chrome.manifest. The component registers an observer for http-on-modify-request topics. The observer’s callback function is called when a new HTTP request is ready to be sent. The function appends into a simple text file located on the user’s desktop a line consisting of the referrer, HTTP method and URL of the HTTP request.

Source HTTP Request Logger add-on for Mozilla Firefox

I don't know whether the output will survive a Firefox crash.

The output is written to http-request-log.txt on the desktop (full name C:\Users\username\Desktop\http-request-log.txt
