Bug 381157 – Make SeaMonkey download manager use toolkit backend
Toolkit provides a downloads backend that is now driven by mozStorage, but SeaMonkey still uses the old xpfe-based downloads implementation. The full bounty will be payed for making the <tree>-based SeaMonkey download manager work with the mozStorage-driven toolkit backend, remove all MOZ_SUITE ifdefs related to that code from toolkit, and have all suite-secific files needed for that in the suite/ directory. For reviews, making the non-download-manager options of SeaMonkey like silent download and per-download progress dialogs work may also be required though.
Note that the Template Query Processor for mozStorage may make this work easier.
As a further note, if you want to go on improving download manager even further (in followup bugs), ideas from the wikiMo mockups and the DownThemAll! extension could be good starting points.
