When you're in classic view, you can access My Uploads via the black bar at the bottom of the page (unless you've disabled that).
AFAICS, if you are in new view in FF, the only way you can get to My Uploads is firstly to go to your own home page, then access My Uploads from there. I don't see how you can directly access My Uploads from a search page or image page.
@Pauws: For me, not having the description directly visible is a killer. (At the moment, I can't see how to access the description in new view at all, but that might be just me).
Also as I mentioned before, for some reason the new view reorders keywords randomly on acceptance, which is a PITA as I try to keyword in order of relevance.
On a positive note, I see that I can access 'manage file' directly from the file page in new view, but IMO that nowhere near makes up for the lack of description and changing order of keywords. I'm currently omitting some of the more generic keywords because of the number of times they somehow land at the beginning of the list in the new view.
