I very rarely run into this in Chrome, they licensed Foxit and made it open source https://opensource.google.com/projects/pdfium https://opensource.google.com/projects/pdfium its native and fast. Firefox I think still uses https://github.com/mozilla/pdf.js https://github.com/mozilla/pdf.js which was not bad last time I used it, but it all javascript so performance isn't up to par with native. Also printing is not great and I don't think they have implemented a SVG backend yet for better printing. On the plus side you can embed it in your web app if you want and have more control over the viewer.
