Firefox Developer Tools ideas

Welcome to the feedback channel for Firefox Developer Tools. This is a place for constructive feedback around the tools with ideas and feature suggestions. It is not a support forum or place to report bugs. For support, please go to the #devtools channel on Mozilla IRC or the firefox-developer-tools tag on Stack Overflow, and for reporting bugs, go to Bugzilla.

The documentation on how the Developer Tools work is available on MDN.

My idea is:

You've used all your votes and won't be able to post a new idea, but you can still search and comment on existing ideas.

There are two ways to get more votes:

  • When an admin closes an idea you've voted on, you'll get your votes back from that idea.
  • You can remove your votes from an open idea you support.
  • To see ideas you have already voted on, select the "My feedback" filter and select "My open ideas".
(thinking…)

Enter your idea and we'll search to see if someone has already suggested it.

If a similar idea already exists, you can support and comment on it.

If it doesn't exist, you can post your idea so others can support it.

Enter your idea and we'll search to see if someone has already suggested it.

  1. Worker debugging for Web/Shared/Service Workers

    The ability to be able to connect and debug JavaScript workers has been missing for some time, but with the advent of Shared- and ServiceWorkers is getting even more of a sore point.

    • Firefox developer edition for android

      I understand that there's a good reason not to bloat the regular Android version of Firefox with developer tools, but why not make a developer edition for the rest of us?

      I can do every other part of my development on my tablet. Why can't I debug too?

      • show web fonts in network tab

        Unless I'm missing something webfonts are not listed in the network tab which is a pretty big omission as they tend to be big and slow and begging for optimization.

        • Save CSS changes from Inspector panel

          Being able to save changes to the stylesheet from the inspector panel instead of the style editor would be an absolute game changer. Emmet LiveStyle that works with Chrome does that, but I haven't found anything that works with Firefox. My workflow is typically use inspector to find object I'm styling, find the line number then edit in Sublime. If I'm experimenting I'll try it out in inspector, then make those changes in Sublime. I'd love if those style changes were just made in browser.

          • Add FirePHP support

            FirePHP enables you to log to your Firebug Console using a simple PHP method call. Actually, Firefox Developer Tools is not compatible.
            All data is sent via response headers and will not interfere with the content on your page. See the protocol : http://www.firephp.org/Wiki/Reference/Protocol

            • Add an option for WebIDE to autoclose HTML tags

              WebIDE's autocomplete and bracket autoclosing work great, but I'd really appreciate it if the HTML editor featured and option to automatically add the closing HTML tag for me so that I don't have to type all those closing tags myself.

              • js coverage tool (like csscoverage)

                I'd like to see a tool to audit the js that actually ran on a page, as a first pass it'd be useful to just get a dump of the js that loaded (ie being able to dump anything that a library only conditionally loads etc.) but eventually being able to remove the code that was parsed, (eg function definitions) but never used (never actually called) would be amazing.

                • Set breakpoints in event handlers popup in the DOM Inspector

                  I'd like to be able to set breakpoints on any line right in the event handler popup window in the inspector tab. Alternatively, having a way to go to the handler declaration in the JS Debugger would work as well.

                  • Highlight on hover network item

                    It would be nice that when you hover over a row on the network tab, it highlights. It is very difficult to line up the data on the row.

                      • Reload Image

                        Many times happen that a page loads but image(s) of page not load. it is better when right-click on has not loaded image, show "Reload Image" instead of "View Image". and also if be possible for image(s) that has not loaded 100% (has loaded incomplete).

                                • Inspector as a full HTML Editor

                                  It should not be too costly to add few more functions to use the inspector as a full live preview HTML editor as many great futures already there for a full "HTML Editor" (more like the great Style Editor utility). Open/save local project folders, editing the HTML page (not just node base) with auto complete/help, redo/undo, find etc..
                                  Maybe some ideas (plugins, dom function outlining..) can be merged from other open-source editors like Brackets.

                                  Please make the DevTools complete with HTML Editor.

                                  • Please add F12 developer tools to Firefox for Android!

                                    I am trying to use a tablet as my principal development device. Others have suggested remote debugging, which is stupid - why should I carry two devices to use my tablet as a development device? They can be disabled by default to avoid issues on lower-end tablets. The tools are already in Firefox, so how hard can it be to make them available on tablets? Also, this is not Valence - I'm not looking to debug other machines, I just want to profile, note js errors, view source, and all that good stuff on my tablet.

                                      • Make them faster and less buggy.

                                        I never use them because they crash immediatly on most sites.
                                        Also often, files are missing (if loaded later), breakpoints are not triggered and so forth.
