Application showing on desktop

[braindmg]

On my desktop the little disk image icons are coming up when i open certain applications. I wanna make them disappear, but still be able to see ipods, cds, and external drives.

Also(somewhat irrelevant), occasionally when i open firefox, it asks me to drag it in the applications folder, but it's already there. please help. its so annooying

If it is already in the Applications folder, than drag that firefox icon on the desktop (it's called a disc image), to the trash to eject it, and then delete that .DMG file, and you'll never see it again.

drag them to the bin to eject them, you'll still have the apps, but those dmgs will be gone
