Revision as of 13:58, 11 January 2012
This page is intended to summarize plans and directions for Firebug.next
This summary should also help FWG to prioritize planned steps and features.
Current status of Firebug development.
Development frozen on this branch.
Firebug 1.9 is the last released version (available on AMO and getfirebug.com) compatible with Firefox 5-11. Selected patches will be back-ported from 1.10.
Development happens on Firebug 1.10 branch (currently alpha).
Goals for Firebug.next
- Improve memory footprint & performance
- Reuse built-in dev-tools API and components
- Innovate features that only Firebug can deliver
New Features for 1.10
This section lists of all suggested areas FWG should focus on in Firebug 1.10
- Firebug 1.10 blockers
- Memory leaks (Zombie Hunter is necessary)
- Fixing memory leaks is still the top Firebug priority.
Delayed Firebug Load
Firebug UI & Logic is mostly running inside an iframe (chrome://firebug/content/firebugFrame.xul). The goal here is to load the content of the iframe on demand at soon as the user needs Firebug the first time.
However there are some pieces that are running within the global Firefox UI (browser.xul) and must be loaded immediately after the browser window is loaded.
- Page context menu (inspector, open with editor)
- Firebug global menu (tool, view, web developer, ...)
- Firebug start button (Firefox toolbar)
- Firebug iframe and a splitter
Firebug iframe content should be automatically loaded when the user presses F12 or uses any command available through an existing menu or a keyboard shortcut. Such functionality requires all global parts to be clearly separated and independent for the Firebug UI itself (the one running in the iframe).
- Separate Firebug UI from Global UI (create separate directory for global parts)
- Create a command dispatcher for global commands that loads Firebug if necessary.
- Initialize global UI independently of Firebug availability (e.g. translations)
- Adapt to the current
Orion Text View Integration
- Remove all code related to Script panel content generation (firebug/js/sourceBox module)
- Integrate Orion Text View
- Create a new Orion breakpoint ruler
- Support for tooltips displaying result of and evaluated expressions under the mouse (based on Orion Text Styler)
Firecookie is a an extension for Firebug that makes possible to view and manage cookies in your browser.
It was required many times to have such functionality included in Firebug by default.
- Firecookie code base doesn't support AMD
- The code should be divided into more (AMD) modules
- Support for backward compatibility can be removed
- Blocking issues should be fixed.
Remote HTTP Monitor
The Net panel should use Remote Debugging Protocol (RDP) to communicate with the server side that is performing HTTP monitoring. This should enabled remote HTTP monitoring e.g. for mobile devices.
The server side script should be using the following interfaces (to monitor HTTP):
- nsIWebProgressListener (monitors the file:/// protocol)
- nsIObserver (monitors http-on-* events to catch also BFCache responses)
- nsITraceableChannel (intercepts response bodies)
- Define new actors and extend the RDP protocol
- Clean separation of the client and server parts
- Communication between client and server based on JSON packets
Restart-less Firebug Extensions
There should be a way how to install Firebug extensions without Firefox restart. This feature doesn't include installation of Firebug extension itself. Some API related to dynamic registration are already available.
- Review API for dynamic adding/removal of panels
- Review API for dynamic adding/removal of modules
- Review extension example
- Update documentation/tutorial
JSD2 (also known as JSDBG2 or JSDBGAPI) represents new API for JS debugging in Firefox.
Jim Blandy and Jason Orendorff are working on a JS implementation of JSD built on top of the JSDBG2 API (a wrapper). This wrapper should be injected into Firebug and make it compatible with JSDBG2. Prototype implementation is available (Firebug 1.9 fork).
Work on this goal depends on how much ready JSD2 is.
Review Internal File Structure
If parts break extensions, they will go into 2.0.
- Convert last few files into (AMD) modules
- Split huge files into more modules
- Suggest places/modules that needs refactoring (e.g. TabWatcher)
Firebug should reuse existing built-in Inspector.
- Investigate API of built-in Inspector
- Investigate related Firebug API
- Replace Firebug Inspector
Net Panel Improvements
Proposed Net panel improvements
- Net panel header should not scroll.
The HTML Panel needs different options how entities are displayed.
There should be three display options inside the HTML panel's options menu:
- Show Entities as Symbols
- Show Entities as Names
- Show Entities as Unicode
- Find out how the API is working exactly
- Implement new mapping function in
Several new features related to breakpoints should be introduced.
- It should be possible to specify how many times a breakpoint should hit before it breaks the script execution.
- It should be possible to create new (and edit an exiting) breakpoint condition in the Breakpoints side panel.
Group Console Messages
Console messages optionally need to be grouped to avoid spamming the Console Panel.
- Group error messages
- Group messages produced by the 'console' object
See the following table that summarizes list of features and dev folks working on them. Append yourself as a developer to features you are interested in to participate.

Please append further suggestions for new 1.10 features in this section so. We'll yet discuss all these suggestions.
Better user feedback
This has been already discussed before. It could be useful to have more feedback from Firebug users and use it for targeted improvements. The feedback should be collected using Testpilot and its related infrustructure and/or through a Firebug extension.
- What specific data should be collected?
- What kind of knowledge we can get from the collected data?
Mapping of URLs to file system paths
Firebug currently doesn't have any connection to the server files. Many people don't understand that and they are asking how to achieve that. This change would at least allow mapping between local server URLs and the file system.
- How is this related to Firediff?
- Apart from Firecookie integration, are there any other extensions we would like to distribute with Firebug by default? (e.g. EventBug, FireStarter, NetExport, ...).
- What further API/Components related to built-in dev tools could be reused by Firebug?
