Yes, but I think Mozilla may have started with code from Foxit.

  The PDFium plugin that was part of Chrome was based on C++ code from Foxit. PDFjs was written in JS from day one, and (as far as I know) was not based on any previous PDF reader.

    Maybe that's what I was thinking of. Thanks. BTW, I didn't mean they necessarily used the actual Foxit code, but it was a starting point maybe reimplemented in JS.

      In no sense is PDF.js related to Foxit except that they are both PDF readers.
