To install the plug-in, do the following:ġ- download the Firefox-Mac-PDF from the link provided above Ģ- open the Add-ons pane in Tools -> Add-ons ģ- drag the just-downloaded Firefox-Mac-PDF (.xpi file) in there Ĥ- you should be prompted to answer yes or no to install the Firefox-Mac-PDF plugin You can also save the PDF, if you wish, but the ability to view it in the web browser saves precious time, especially if you need this feature quite often.Īvailable right HERE, this Firefox extension works only with the latest version of the Mozilla's popular web browser, Firefox 3. There's even a new addition for Mac, a plug-in, which allows PDF-viewing right from within the browser. Everyone can agree on that Firefox 3 is off the charts, as far as coolness goes.
