Upgraded Firefox from 2 to 3 this morning and just noticed that the white crosses on black circles that allow tracks in 'Profile Music' to be removed are no longer visible to me. I tried altering font sizes (which worked for getting the Tunebox 'Send!' button to appear) but with no success. I have checked the site with IE7 and the crosses are visible/accessible in that browser. I'm using Firefox 3.0/Win XP SP3.

It's fixed for Firefox 3 (make sure to refresh).

By the way, you can overwrite the existing tracks by just dragging the songs over your profile music.

All fine now thanks Sam and thanks for the pointer re. overwriting songs.
