I do the same thing as you, but for me the "save target as" still works fine (yesterday at home and on my office pc right now...).

The only thing what changed for me is that the names of the pics of newer items are much longer. They start the same as the old ones but then there is a 'new' large string of characters and numbers added. I have to use a rename function to get the same format that my older downloads have.

I am using Firefox btw...
