So what do you want in Firefox 3.0?
We are currently in the early development stage for Firefox 3, and would like to collect all the ideas for feature enhancements in a single place. Our goal is to create a single index that lists what sorts of things we're thinking of doing, with links to more detailed ideas about implementation specifics or concerns, and targets for inclusion in the project.http://wiki.mozilla.org/Firefox/Feature_Brainstorming
Note: This is a list of feature enhancement ideas for all future Firefox releases, not just Firefox 3. Firefox 3 will include a subset of the items on this list.
