Firefox/Features/Replace old profiles

Feature	Status	ETA	Owner
Replace Old Profile for Returning Users		YYYY-MM-DD	Owner Name

Summary

Firefox is old enough now that many users of Firefox have since moved on to other browsers. When they return to give Firefox another try, they're returned to their old and probably useless (and potentially even broken) profile. If a profile has not been used in a long time, Firefox should discard it and offer the user a migration from their current default browser. This will give them a modern Firefox profile with their contemporary data. Without this, users are likely to return to their default browser where their contemporary data lives.

Risks

Use Cases

Marcos used Firefox up until version 3 when he decided to switch to Chrome. He's been using Chrome for a couple of years now but heard that Firefox 4 was blazing fast and had some great new features. He downloads Firefox but when he launches it, it has his three year old Facebook and Bank of America passwords stored which don't work any more. It's also missing all his new favorite websites and what's even worse than that is the awful Ask toolbar that just showed up in Firefox one day back in 2008. He decides Firefox still sucks and goes back to Chrome.

Julia was a Firefox 4 that decided to Give IE 9 a try and found she loved it. Since moving to IE 9, she's amassed about 1500 new favorites and a bunch of new logins. Hearing that Firefox 6 is the bomb, she downloads it. When starting Firefox for the first time, it asks her if she'd like to migrate her IE 9 settings and data. She says yes and Firefox does. She has no more reason to go back to IE 9 and so she makes Firefox 6 her new default.
