Comment (by cypherpunks):

 The blank page is a new error that affects other browsers as well.

 The original problem is that document.createElement('a').origin is '' and
 therefore when mega inserts a blob link it has the wrong origin for the
 new blob restrictions in 5.0.  I'm having the same problem with a
 greasemonkey script inserts a blob link. Clicking the link does not
 download the file in the blob like it did in 4.5.3.
