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. 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).

      • Fix the debugger

        I appreciate the aim to come up with something new and useful. However IMHO the core tools should be working and reliable first. There are plenty 'NEW' old untouched issues regarding debugger in bugzilla. See https://wiki.mozilla.org/User:Dria/TestTracking#Developer_Tools:_Debugger . E.g. debugging content scripts of addons or attaching sourcemaps or debugging dynamically loaded scripts.
        So please address existing debugger bugs.

          • Google using your software? Bookmark repair in Chrome lead me to Firefox repair instructions.

            Used to be Bad thing, many moons ago. Plagiarized (sp) or whatever.
            Or is it all share and share alike? You run with it. I'm just letting you know.

              • Operation Interceptor

                There is a huge problem in the works with all of the Mozilla dev tools/api. We need to intercept the goals of these tools and reroute them using common sense and logic.

                Whoever decided that the JSREF move over to C++ was a complete numbskull. Perhaps it makes the software development easier, but High Level Language does not EVER make good API binding in terms of general applicability. It pushes more dependencies on the disinterested developer and requires him/her to invest significant resources on insignificant details that have nothing to do with the goals or aims of his/her project.

                Moreover,…

                • Show requests to indexedDb in Network panel

                  Chrome tools displays requests to indexedDb in the network panel with the option to filter them out. I consider this very helpful

                  • 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.

                            • Better JS debugger

                              I want to have better JavaScript Debugger. I love Firefox for its simplicity but JS debugging in native devtool of Firefox is not as good as other tools. What I really want is a way to get accurate call stack of functions better error information and way to go to method declaration.

                              • Prettify html when editing in inspector

                                The "edit as html" option in the inspector context menu is a good idea, but it isn't very useful for the following reason:

                                My main use case for this option is to edit some html that was created by javascript, and therefore does not have line breaks or formatting. In the inspector, everything is well formatted, with a dom tree and proper indentation. However, when I choose "edit as html" from the context menu, all the formatting is lost. It just becomes a huge string of html that is almost impossible to edit. The debugger can already prettify code -…

                                  I’d love to know how an element gets its position. If it’s in an absolute position knowing the context (ex. the parent element having a relative position).

                                    • Allow live edits of svg to be visible in 3D dev tool.

                                      The 3D tool is good for visualizing a svg page.
                                      Then changes to the viewBox are not reflected in the 3D view.
                                      This would aid greatly in understanding the window viewport settings and impact of viewBox changes.

                                      • Show actual pixels painted in paint events in the profiler

                                        The profiler shows paint events in the timeline, but there is no actionable information. I'd like to see a mini-screenshot of the actual pixels painted so I can see when the same region is being painted to much.

                                        • clear button design

                                          Clear button looks in different location in network panel and console panel. also it is easily confused with the dropdowns in console panel. Please user an Icon instead of clear text I think every body can easily understand a trash can or similar icon's meaning. Also please move it to the top of the panels. it's hard to move the mouse to the button specially when auto hide dock is used in Macintosh.
