View PDF file in Firefox using the built-in PDF viewerThe built-in PDF Viewer in the Firefox browser is quite enough for the users to view the PDF document, as it doesn't take up any extra load and saves a lot of time, without the need of downloading and opening the external app to view the document. This PDF viewer is enabled by default, and you would have to dig a little into the internal settings if you don't want to use this viewer, and wanted to download the PDF file before opening it, although there is an option of saving in the viewer.
Features / functions in the built-in PDF viewerThere are quite a few features of this viewer, and it doesn't end with just displaying the PDF file. Here's what all the plugin does. Zooming in and out - comes with the direct options to zoom in and out. There is also Automatic Zoom options, and the user can select a particular zoom or select to see PDF on the page width or the page fit size. Page up / down & Skipping to a page - the user can go up and down the different pages in the PDF using the options, and also can skip directly to a particular page by typing the number. View page thumbnails - For those who don't have an idea of which page they directly wanted to skip to, there's a thumbnail viewer that opens on the left side and the user can quickly scroll through that before selecting the actual page they wanted to read. Options on the right corner - There are four options which are really helpful in doing the stuff that you would want when you don't want to end it with just the reading of the PDF - download the PDF file to the computer, Print it directly from the browser, switching it to the full screen mode and opening the current view in the new window. You can open the pdf in full screen view, and this is a good part considering that you don't need to install any third party apps or plugins to do this.
