Nodobe Viewer is an interesting extension for Mozilla Firefox, light and free, which will allow us to view PDF files. The advantage is that it takes up very little space on the hard disk, unlike Adobe Acrobat, and it is also an SUV that operates on Windows, Mac and Linux with up to 38 varieties of document and image file types. These formats are: PDF, DOC, DOCX, RTF, XLS, XLSX, PPT, PPTX, PNG, JPG, GIF, TIF, BMP, PPM, XPM, EPS, RAS, TXT, ODT, ODF, OTT, ODG, ODP, STW, SXW, STD, SXD, STI, SXI, SXC, SDA, SDD, SDW, VOR, OTG, STP, ODS and PTS.
Nodobe Viewer allows you to view Microsoft Office documents, OpenOffice, images, and so on. For this we are likely to have to register on the author's page. Apart from this small inconvenience, Nodobe Viewer is a tool that is very worth trying.
You can free download Nodobe Viewer 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
