Firefox3/Gecko Feature List

Firefox 3 / Gecko 1.9 Feature List

This page is intended to collect the set of features that either have gone in to Gecko 1.9 since Gecko 1.8 was branched, features that people are working on, or features that people intend to work on for Gecko 1.9. It will eventually be migrated into the Gecko 1.9 Requirements document.

The content from Gecko_1.9_Alpha_Planning has been merged into this list.

Cocoa Widgets on Mac	P1	josh
Landed 2006-09-28. Regressions

Fix units in Gecko	P2	Eli Friedman
Landed.

Reflow branch	P2/P1	dbaron

DOM

Language-agnostic DOM	P1/P3	Mark Hammond

SVG

SVG as image format	P3	unowned
Work is mostly in docshell/imglib/etc. See what SVG status is.

Networking

Cross-domain XMLHttpRequest	P1	jonas
Feature would be a P2, but it's important enough for web apps that it's a P1.

Platform

Firefox on XULRunner (and shipping XULRunner platform)	P3	bsmedberg
In Progress; we can ship without it, but the main advantage is to shipping XULRunner to all Firefox users and so providing the Gecko runtime to any app.

Killing nested event queues	P1	darin
Landed; need regression bug link.

Graydon's Cycle Collector	P1	graydon
Re-landed after being backed out for perf issues. Landed 2006-11-22. Regressions (Will improve memory footprint only once it's hooked up to components and if there are cycles where it can help, but only once the components and the cycles are analyzed. Part of this involves investigating potential wins for memory footprint in components.)

XPCOM restart in-process	P3	bsmedberg
Can work around Mac issues with double-restart without this.

Cache item pinning for offline support	P2	unowned
Includes robust offline/online detection mechanism.

Offline web browsing	P3	unowned
Improving cache behaviour and browser behavour when the user is offline.

Accessibility

ATK support rearchitecture	P3	aaronlev,ginn.chen
Landed.

Mac OS X Accessibility support	P3	hwaara
In progress, just started on the foundation.
