- This page is intended to summarize plans and directions for Firebug.next
- Provide any feedback on Firebug newsgroup
This section describes the strategy and goals that keep Firebug a competitive in-browser tool and leader in space of in-browser developer tools.
 Version Numbering
The next planned version number is 1.13.
Development happens on
master branch (currently alpha).
If a significant new feature (or set of features) is introduced in new release, the version numbering can move into 2.* scheme. An example of such a feature can be support for JSD2 or even remote debugging.
- The entire release cycle (from the first alpha to the final release) should target 6 months
- The beta phase should be at least 4 weeks
- The new release should introduce 8-10 new features (or significant bug fixes)
 Suggested Features
Use this section to suggest any feature you'd like to see in Firebug.next.
- Remote Debugging (reason: allows debugging on mobile devices; built-in dev tools already have this)
- Undo/redo option in HTML panel (+ CSS + DOM if possible) (issue 54, issue 2569; reason: people should be able to easily undo mistakes; built-in dev tools already have this)
- Cut option in HTML panel (issue 6217; reason: we already allow to copy HTML, OS conformity)
- Ignoring scripts while debugging (aka "black boxing", issue 4888; reason: makes debugging easier; built-in dev tools already have this)
- New inspector (issue 4848; would fix a bunch of problems; built-in dev tools already use a better approach)
- Display of pseudo-elements inside HTML Panel (issue 5785; reason: better UI and fixes issues; built-in dev tools have this now)
- Linux theme (issue 471; reason: better integrated UI for Linux users)
- Request auto-responder in the Net Panel (issue 6459; reason: makes much easier to debug response headers and JS files in a production environment).
- Integrate EventBug into Firebug (issue 5440; reason: simplifies debugging of event listeners)
- New screencasts! (issue 4508; reason: current screencasts are completely outdated, new features need to be described)
- User statistics collector (2633; reason: get info about Firebug usage to get a clue how to improve the UX)

 Feature Description
This section provides detailed description of all planned features.
 Adopt JSD2
Firebug script debugger and all related features like BON (break on ...) should be based on new JSD2 API. Using JSD2 API will also enable remote debugging.
Part of this task is also internal Firebug architecture refactoring so it's ready for remote debugging features. Note that adopting JSD2 doesn't automatically mean that Firebug is remote-debugging-ready. This is covered by issue 5837
Note that this task doesn't have to make it into Firebug.next, but it could be possible (if useful) to at least merge code changes.

 Auto-completion for Command Editor
- Allow auto-completion within an expression
- Add auto-completion to the Command Editor
- Enhance positioning of the Completion List Popup
 Line numbers in CSS Edit Mode
The Source Edit Mode of the CSS Panel should have line numbers for easier navigation.

 Folding for shorthand properties
For shorthand CSS properties it should be possible to expand them to see the longhand properties that make them up.
- Save the longhand properties to every shorthand property
- Create a twisty and allow toggling the display of the longhand properties
- Remove the Expand Shorthand Properties option
 Sniff WebSocket traffic
WebSocket requests should be displayed to the user.
