For me it's the opposite. Firefox's dev tools feel better. What things are missing?

What cripples FF DevTools for me is being unable to find the setting for timeout on HTTP GET, during full-stack development. If I've set a breakpoint in a debugger on my server and proceed to single-step there, FF aborts the GET request with an error. So client-side JS doesn't see the eventual result of the GET, it has to recover from the error to proceed, e.g. by a full page-reload.

Chromium, last I tried it, by default sets the necessary HTTP timeout(s) to infinity if its DevTools is open.

My searches of Firefox docs/wiki, StackExchange, HN Algolia for a fix have come up empty.

Navigating to "about:config" and searching for "timeout" finds 27 different settings prefixed with the substring "network". Some are obviously in units of milliseconds, others perhaps whole seconds.

Anyone know which one (or what combination) might incant the necessary black magic?

One of the reasons I stopped using Firefox was that the columns in the devtools were unexpandable. I couldn’t see any data past what Firefox decided was enough to show. Did they fix this?

I'm assuming you're talking about table views like the Network or Storage/Cookies tabs? You can resize columns and each cell has a tooltip that shows the full content if it's hidden.

I really like that the Chrome profiler shows you the profile right there. Firefox insists on opening the profile in a browser tab. This is fine, but is an unnecessary context switch for me.

On Chromium touch screen emulation feels much better.

I find them both pretty poor compared to running on emulators/simulators

I use the FF devtools daily, and for what I'm working on, it has everything I need to help me get the things I need done. Knowing that I'm not everyone and have plenty to learn, what things are missing from the devtools for you?

I use FF and prefer the devtools.

Chrome's ability to temporarily edit and save changes to JS sources through the debugger editor is fantastic though.

Other than that it's mostly just improvements to what FF already has.

Search could be made much more useful, especially network requests. Searching all request bodies/responses for a particular string/json/regex would be a huge step up.

You can search the response of individual requests but there's a UI bug that makes it look like your filter is no longer applied when you select the next one in the list.

Does this affect the live code so the change is available immediately? I once had a thought about wondering if this was possible to have the change available without refreshing

As far as I know, you have to reload the page sadly.

It made no sense for how that could work that I could imagine, but it would be holycrapthatscool if it could. some sort of second JIT or something, but i can only imagine the security nightmare that'd open up

The only issue I have (which, is happening less and less lately) is my debugger doesn't jump to the source. It hits and everything pauses, but I don't get routed to it and have to start progressing just to get it to work, which can make the debugger useless as you've gone past what you were looking at. This has happened across machines for years for me, and happens much less in chrome. But doesn't happen enough for me to switch.

Me too. I'm using FF since 3.6, and before that Camino (a derived version for the mac), and the only thing Google has done is strengthen my resolve to keep using Firefox, but I still prefer to debug on Chrome (well, Chromium). It just feels better, even though it's starting to slip and FF is improving slowly.

Give Firefox Developer Edition a try, if haven't already, and are looking for more robust development tools.

Looking at https://www.mozilla.org/en-GB/firefox/developer/ I'm a bit confused... Which features are just new features which will soon be in the main Firefox DevTools, and which are specific to installing the Developer Edition?

AFAIK, Firefox Developer Edition is currently just a repackaging of Firefox Beta and doesn’t have different devtools. It used to be a rebranding of Firefox Aurora (an alpha release channel between Firefox Nightly and Beta, now retired) with a different theme and a few different devtool setting changes.

Maybe I was just unlucky, but the one time I tried it, it refused to launch.

I'd rather not have my professional work tools be built against a beta channel when there are better alternatives.

I have been using the Developer Edition since 2014, when it was released, without issue. You are not locked into a single browser. Personally I use more then one browser, and professionally I always validate against multiple browsers.

I find different browsers excel at different things in regards to the developer experience. As an example I appreciate that Firefox had a formatted JSON view without requiring an extension. However Chrome also has capabilities that I wish were included in Firefox.

What are the differences compared to regular Firefox?

Firefox Developer Edition is targeted towards developers, and contains the latest development tools available.

New features also land quicker, as it is built against Firefox beta.
