It looks like there has been a revamp of the My Uploads page.  The controls we are used to seeing are (very counterintuitively) placed on the bottom left side of the screen now instead of above.  Sean's lovely greasemonkey script doesn't seem to be working with this new arrangement either. 

Ah, okay.  Looks like Greasemonkey got turned off somehow.  Not sure how that happened but I just re-enabled it and it looks fine now. 

BTW, Sean,  I had forgotten what a monstrosity that page is without your greasemonkey script.  Thank you once again for making it
