I have been happily using "ISBN Linker," an add-on that I heard about from a few different sites and installed from Mozilla's "Add-Ons" website only a few months ago. I went to the site today to install this add-on on a new computer, and I received the message that nothing could be found under that name. As far as I can tell, it's been entirely removed from the add-on repository (Google Cache still shows some remnants of its existence).

Is there any way to find out why it was removed? It's not that I want to argue for why it shouldn't be there, but rather that if it was simply that it hadn't been updated, or perhaps that it was even just removed by the creator, I'd take a shot at re-creating the add-on and resubmitting it. If, though, it was removed for some other reason, I'd love to know so I avoid any problems!
