This completely slipped off my plate, sorry. Feel free to ping me directly next time. The feature has already landed as you might know but I'll still try to answer some questions to get this done....

Yoric and me I guess. There's also a couple more people in the Fx Desktop team that know how it works.

The thumbnail service captures thumbnails of pages the user visits to use them for various features in the product (e.g. about:newtab). We're also currently preparing a background service that will be able to load privacy-sensitive pages in "private mode" (without any cookies, etc.) to capture screenshot of those pages (bug 841495). We currently don't capture thumbnails of Facebook but with the new feature we'll capture the start page of it, without the user being logged in.

Firefox. It's recently been moved to Toolkit so that Metro can use it, too. And maybe other products in the future.

No.

> 10) Will your application/service collect user data? If so, please describe

Yes, screenshots of pages visited, stored in $ProfLD/thumbnails/. We do not capture thumbs for pages that send a Cache-Control:no-store header (bug 850685) but we currently still do for pages that for example have a CC:no-store iframe (bug 823829).
