JavaScript code override under developer tools

[SmartBastard]

In Chrome, there's an option "Enable Local Overrides" (while in inspector). When switched ON, we can edit, remove and inject JS lines to the files that are hosted with the website and/or we can add our files with custom JS code. Thanks to that, we as developers could debug JS code on the site. That's the only reason why I can't switch to Firefox on 100%.

Yes I am having the same problem in latest version of Firefox.
I added a script override, but it won't let me edit code within the Devtools, and changes saved on the local file aren't being applied.

Not yet?

Same issue as Chad3 described but on Firefox 133... Got the purple dot but the local file, which has been edited and saved, is not being used.

You have to reload the page to see the effect.

You have to reload the page to make it load the override.

Doesn't have any effect for me. It still doesn't use my override.

@Chad3 There is a documentation for Network overrides available here (Including notes about overrides in the Debugger)

https://firefox-source-docs.mozilla.org/devtools-user/network_monitor/network_overrides/index.html

Does it help?

If it's still broken for you, can you please file a bug here:

Thank you!
