Viewing PDF in browser

Sometimes when I click on a PDF file link, it opens in the Firefox, but sometimes it does not, and Firefox instead asks where to save it, which is annoying. Why this inconsistent behaviour? How can I view the PDF files in Firefox every time?

Only files send as content type application/pdf are opened in a tab in Firefox.

If a file is send as a generic file type like "application/octet-stream" or as content-disposition then Firefox will offer to save the file.

Great! Thanks for the swift and helpful reply.

I tried the "Open in Browser" extension first and it half-solves the problem. Firefox still shows you the save dialog, but the extension gives you the additional option to view in browser. That's the same number of steps I had to make before, so nothing gained.

Mason sounds like a very powerful extension, but is overkill for this situation.

"InlineDisposition Reloaded" was exactly what I needed. When there's a PDF in my google search results, I simply click on it and it opens as expected. Very lightweight at 4kb.

Yup, Always Preview seems to work equally well.
