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%.
Thanks for submitting an idea to the Mozilla Connect community! Your idea is now open to votes (aka kudos) and comments.
100% agreed, this is great feature and we are currently working on it (or at least light way version of it)
Bug 1704690 - Local HTTP Response Overrides
Btw. what is the use case for you? Are you debugging foreign web site? Or your own local site?
This idea was shared with our DevTools Engineering team, and we're excited to report back that it is being worked on. Check out @Honza's comment in the thread for more info and stay tuned for updates 😀
