1547689 - Persistent selection of iframe as target document

Status: NEW

(DevTools :: General, enhancement, P3)

Description

[Filip Štamcar]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:68.0) Gecko/20100101 Firefox/68.0

Steps to reproduce:

I have some website which contains an iframe. I can point the developer tools at a specific iframe within a document with the button in the toolbar. This works.

Actual results:

When I reload the website, developer tools are pointed back to the main document. If I still want to use iframe, I have to point the developer tools again.

Expected results:

Developer tools should remember currently chosen iframe and use it even after reloading the website.

This sounds useful indeed. Thank you for filing this enhancement request.
I think the way to go would be to remember the target frame with some kind of unique identifier, so it can be re-selected after reloading the entire page.
Something similar is done for re-selecting DOM nodes in the inspector today: https://searchfox.org/mozilla-central/rev/7944190ad1668a94223b950a19f1fffe8662d6b8/devtools/client/inspector/inspector.js#1190-1230

Note that on some websites, iframe URL contains random "nonce". In this case, iframe's URL will be different on each request.
Is it possible to also handle this?
