I installed Flashget with its Firefox integration. Whenever I would download something I would get a oage that said "The download has been transferred to Flashget" and, sure enough, Flashget would start downloading it.

However, I really didn't like Flashget and uninstalled it. My downloads are still saying that they're going to Flashget (except nothing happens). I deleted all instances of Flashget and Jetcar from the registry, but I don't know how to make Firefox stop thinking I still have Flashget.

Did u restart firefix after deleting flashgot ??

Yes, I restarted everything, including the computer.

and i taking it that u deleted flashgot through control panel > add remove programs ??

Yes.

First I uninstalled through "Add/Remove Programs"

Then I deleted all registry instances of "FlashGet" and "JetCar"

Then I rebooted the computer.

Then I posted on Neowin.

There is propably that flashget plugin still installed in your browser, go to Tools -> Extensions and look there. If you find that flashget there, select it, press "Uninstall" and restart Firefox.

install a different download manager or uninstal and reinstall flashgot

I thought that would be it, but no suck luck. It doesn't appear in my extensions.

make a new firefox profile

Flashget=Spyware, you didn't know that?
