Steps to reproduce:

I opened the network information in the development tools, and I requested an Web site, via the HTTP proxy of my company (the FQDN is not resolved by my company DNS).

Actual results:

In the network information in the development tools, I found no information about the HTTP proxy. This is very annoying, because, as a developer, I'm not able to distinguish the request which passes by the HTTP proxy from the direct HTTP requests (for the FQDN not resolved by my company DNS).

And in the generated scripted requests (curl, etc.), there is no proxy parameter. Therefore, many scripted requests are not working.

Expected results:

In the network information in the development tools, there should have a field indicating the HTTP proxy that is used (or "direct" if no proxy is used).

And the proxy parameters should be in the generated scripted requests (curl, etc.). Maybe with the proxy password replaced by "http_proxy_password", by security.

The Bugbug bot thinks this bug should belong to the 'Core::Networking' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

I think this is worth mentioning in https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Releases/117.

Also the docs at https://firefox-source-docs.mozilla.org/devtools-user/network_monitor/request_list/index.html should be updated, so people know about that feature.

Docs additions for this can be tracked in the following GitHub issue: https://github.com/mdn/content/issues/28755

There's a PR open to add a note to https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Releases/117 linked above although I cannot see the proxy information on local tests with nightly 118.0a1 in the Headers tab. Are there any steps to reproduce/demo this - requirements for the proxy setup (HTTP version, other headers)? Thanks

Hi Brian,
Please did you try collapsing the Url Preview section by clicking the HTTP method? See the attached image

Thanks Hubert, the screenshot is helpful, but I don't see this with my local tests (I've tested using https://github.com/http-party/node-http-proxy with ngrok and some other packages with no joy), maybe it's something odd with my network configuration or system setup.

The release note is now merged at https://github.com/mdn/content/pull/28761. I'm not setting dev-doc-complete yet as I don't know the status of the firefox-source-docs additions.

The firefox-source-docs were not updated yet. Bomsy, do you intend to update them in this bug or should I file a new one to add them?

Hi Brian,
Hmm interesting, what does your network configuration look like? Also have you tried with a proxy tool e.g Proxyman (https://proxyman.io/)?

Hi Sebastian,
No i didn't intend to use this bug. Lets file a new bug for adding the documentation.

This works as expected with proxyman using SSL proxying, it's likely improper setup on my side, thank you.
