Foxit Reader is a leaner and meaner alternative to Acrobat Reader for reading Portable Document Format (PDF) files. I’ve been using it for some time but disliked the fact that PDF files opened outside of Firefox. Finally, while trying to view my credit card statement online and having it complain about needing to install Acrobat Reader, I decided I’ve had enough.
I googled for a solution and found out about the Foxit Reader Firefox Plugin. I looked for it at the Foxit Software website to no avail. Finally I found instructions on how to install it: After downloading and installing Foxit Reader, run it then click Help->Check for Updates Now. On the tree view, you will see the plugin. Select, add, and install it. You may need to restart Firefox but once you’re done, you can now view PDF files from within Firefox. Problem solved!
