What is happening with asm.js?

  is there something which should happen?
- valarauca1 12y ago
  I don't think its mentioned because nothing changed in FF31 concerning it.
- asadotzler 12y ago
  It's getting faster.
- JohnTHaller 12y ago
  It's still awesome. And it's benefiting from the speed improvements in the rest of Firefox even when a release is done without specific asm.js enhancements.

Firefox dev tools are becoming better and better. I disabled Firebug a few weeks ago, I don't miss it.

  I still use Firebug for Cookie management. I have to try if FF tools support that

    It's still not there in Firefox 32, but I read somewhere that a resource manager is planned (including localStorage etc.)

  A part of me is annoyed that Firefox has spent so long trying to build a set of dev tools when Firebug was already an established tool for them. I agree that the dev tools are a lot better, and I've recently removed Firebug as well, but I've spent many months annoyed at Firefox dev tools appearing when I've wanted to inspect an element using Firebug. Firebug has been a resource hog for a long time now, but I feel that I stuck with it for longer than I should have because the Firefox dev tools were an annoyance. Is there a specific reason why Mozilla didn't just ask the creator of Firebug if they could merge his work into the Firefox source, and build on the creators already good work.

    We thought long and hard about including Firebug wholesale and considered several approaches to integrating it. An early prototype of the Inspector even included a significant portion of Firebug. Ultimately, integration proved to be too challenging and would have required rewrites that would have been equivalent to starting over.

Something I don't get about the Firefox developer tools is why they make the console logging unavailable if I've defined console as a window level variable, overwritten for the purposes of extending its behavior. This only happens for the Firefox tools. Firebug, Safari and Chrome web inspector don't care. We do this so we can enable and disable console statements for debugging purposes. We monkey patched console, and because of that I can't use Firefox developer tools at all. It's a shame.

  Works for me: > c = console Console { } > window.console = {} Object { } > c.log("hello") undefined "hello" If you could provide specific steps-to-reproduce and/or a test case, then dropping those in a bug is the best way to get the behavior fixed: https://bugzilla.mozilla.org/enter_bug.cgi?product=Firefox&component=Developer%20Tools%3A%20Console https://bugzilla.mozilla.org/enter_bug.cgi?product=Firefox&c...

  Have you created a minimal test case and filed a bug?

Awesome, I've been waiting for "copy as curl"! The dev tools are improving steadily. Using the xmonad window manager the color selector window gets sent to the background. Perhaps this could automatically work if the color selector window provided Extended Window Manager Hints? If not, does anyone know the name of the window the color selctor opens so I can make the color dropper work by forcing it to float?

  The eyedropper is using a panel with a call to openPopupAtScreen to open it (http://dxr.mozilla.org/mozilla-central/source/browser/devtools/eyedropper/eyedropper.js#195 http://dxr.mozilla.org/mozilla-central/source/browser/devtoo...). I'm not sure exactly in what ways this is failing, but please file a bug under "Developer Tools: Inspector" if you have STR and we can try to narrow it down: https://bugzilla.mozilla.org/enter_bug.cgi?product=Firefox https://bugzilla.mozilla.org/enter_bug.cgi?product=Firefox.
