Full Firefox Integration in Songbird

Firefox is by far my most used application. iTunes is probably my second most used application, but I discovered Songbird. Songbird is by no means perfect, but it will get better every day as an open source application. Since Songbird already has Firefox integrated into its interface, why not find a way to integrate Firefox and all of its add-ons for use in Songbird?

I have noticed that some popular add-ons have made their way from Firefox into Songbird's Firefox, but why not integrate the non-theme portions of the Firefox add-on database into Songbird? I think working on integrating the database into Songbird would be more productive than porting individual add-ons. I don't know if this is possible, but its an idea I though I should share.
