"IE view" and "PDF Download" Firefox Extensions

Feel more comfortable with these two Firefox extensions:
IE View:

Adds "View page in Internet Explorer" links to the content and link context menu. Handy for previewing pages in IE, loading up IE-only pages when you run across them in Mozilla, etc.

PDF Download:

Allows to choose whether you want to view a PDF file inside the browser (as PDF or HTML) or you want to download it
