Product summary

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".

Worked well until recently. Instead of opening pdf links in a tab, now I often get prompted to download, which is the main thing I want to avoid - cluttered downloads.

とあるサイトの添付PDFが必ずダウンロードになることを防いでくれるので重宝しています。 わざわざダウンロードまではしたくないことが多いので、無駄を省くことができました。

Bem melhor que o nativo do chrome para selecionar textos, fora que não preciso ficar baixando pdf para ler, consigo ler antes de baixar e depois decidir se quero

This is the PDF extension you want to install. It 'just works'. It gives me exactly what I want. Full page view, same shortcuts as Acrobat. I made the big mistake of installing the Adobe Acrobat extension. All I wanted was a PDF viewer that behaved like Acrobat, meaning that I could get a full page view and use Acrobat shortcuts to navigate. But no, I got a tiny multipage view with no shortcuts. Typical complete Adobe fail. I uninstalled it immediately and installed this extension instead.

Works great! The default PDF viewer in Chrome is complete garbage. This extension brings the Firefox PDF viewer to Chrome. I only wish it would not change the favicon of the tabs - distinguishing between multiple PDFs is now a tiny bit more difficult.
