PDF.js is a Portable Document Format (PDF) viewer that is built with HTML5.

PDF.js is community-driven and supported by Mozilla. Our goal is to create a general-purpose, web standards-based platform for parsing and rendering PDFs.

This extension offers PDF.js as the default PDF viewer in Chrome. This is the official Chrome extension of the PDF.js project. Be careful of unrelated copycats.

If you want to use this viewer to view local files, visit chrome://extensions/?id=oemmndcbldboiebfnladdacbdfmadadm and put a check before "Allow access to file URLs".

I really like the viewer, but I find that it is slow in loading PDF files, and also slow in responding to zoom-in and zoom-out commands. Is there a fix for this?

to my experience the main problem is that it change the link in the path and if I want to copy the link after PDF page was openned it's a bit challenging.

Great, force open links that are downloadable by default chrome view. However the default viewer has better rendering for the small fine details when zoomed out that this extension.

Very good. however, it is better, if the toolbar can be hidden (automatically and/or manually).
