MuPDF solves a bit of the same problem, in that it renders PDF while trying to ignore all the extensibility cruft that makes Adobe's PDF reader incredibly insecure.
> Maybe you know that there is no default PDF viewer in the Opera Browser, something we would like to change. But how to include one? Buy it from Adobe or Foxit?
If that is the problem being addressed, then I think it does?
One can ask if patching MuPDF vulnerabilities is a bigger hassle than getting PDF.js performant.
MuPDF is a very nice piece of software, but it's GPL licensed. As I understand it, this basically prevents MuPDF from actually being used in commercial software ... unless of course we would make the software open source ...
It's not GPL. They commercially license it if needed, but my understanding was that Opera is open source and would be compatible with the license on it.
