Always open PDF in Browser
If I open a PDF from the downloads section of this page: example pdf (all the way at the bottom) I get a popup asking "What should Nightly do with this file?". I always want to open the pdf in the browser, that's why I checked the box next to "Do this automatically for files like this from now on.", however I keep getting the same popup over and over again.
This only happens for some links (e.g. the one I provided).
Is there any way to open *all* PDFs by default in Firefox?
Thanks in advance.
