Storing Blobs into IndexedDB

Is here anyone who is using IndexedDB to store blobs?

I'm porting my extension that stores images as Blobs into the IndexedDB but after each extension reload, some of the images stops loading (I use URL.createObjectURL(blob) to create image link). Note that same code works in Firefox and Chrome.

Also sometimes update fails with error:
Error preparing blob/file

If this is a known problem, I will refactor it back to Data URL strings :(.
But I'm still hoping this is just some development-mode related issue...
