None of the 8 bugs related to this seemed to have an overarching view that I wanted, so let's use this bug.
The goals of this feature are:
1) Improve the guided bug entry screen itself (bug 1050232)
2) The revised guided bug entry screen will attempt to filter out web devs (bug 1050224). Web devs will directed to "a more focused set of product/components t" (bug 1050226). For core bugs, ask questions at the final step of filing a bug (Bug 1050235)
3) At the end of filing a bug, there should be checkboxes that trigger certain keywords (Bug 1050252)
4) Detect nightly users and offer them "recently filed" bugs, in addition to "possible duplicates" (Bug 1050259). Nightly users will also have an additional keyword checkbox (Bug 1050255).
