Open issues/risks

Other browsers all migrate Firefox settings and data. We are surely losing lots of potential users here.

Stage 1: Definition

1. Feature overview

Firefox offers new users migration of settings and data from Internet Explorer, Safari, and Opera. It does not offer users migration from Chrome. It should.

The goal is to make Firefox a seamless conversion from Chrome.

This feature falls primarily in the Experience category (from the "Discover, Experience, and Connect" vision statement.)

2. Users & use cases

All users new to Firefox who have a Google Chrome profile on their system.

A Chrome user wants to try out Firefox so he downloads it and installs it. Unfortunately, for him and the 150 million other Chrome users who might want to try out Firefox, his Chrome settings and data are not migrated so when he goes to log into Facebook and his username and password are not pre-filled, he says "screw it" and returns to Chrome.

3. Dependencies


4. Requirements

Users, on first launch of Firefox, must be able to migrate their Chrome passwords, bookmarks, history, form data, cookies, and applicable preferences/settings.


The goal is not to keep Firefox in sync with Chrome, just to migrate it one time.

The goal is not to provide post-firstrun importing of all of these settings. If that is easy to do or otherwise comes along "for free" that's great. This feature does not require that.

Stage 2: Design

5. Functional specification

When a user installs Firefox and launches it for the first time, the Import Wizard is launched.

The Import Wizard should include an option to import Google Chrome settings and data (along with any other installed browsers).

Selecting Google Chrome from the list of browsers in the Import Wizard and clicking "Next" should result in the wizard importing the user's Chrome passwords, bookmarks, history, form data, cookies, and settings.

6. User experience design

No change from the current Import Wizard that users already get for importing from the various other browsers.
