Stack Gives Back I'm having the same problem right now. It wasn't happening roughly days ago though. Up until now PDF's were opening up fine.
Please stop posting comments here. There's been nothing to suggest that this isn't covered by existing bug reports. The reporter made it seem like the issue was occurring under new circumstances, but here's been no follow-up, so this should stay closed as Incomplete. Copy Summary.

I had to use the link for the newer version of Firefox 57 , and I did select the Adobe Acrobat DC default option, but it didn't fix my viewing problem.
Thank you, also, jscher I have only been dealing with one site so far. It's a Thinkific online course site that I use to create courses, and I have always been able to open and view PDF files on it via Firefox until yesterday. Firefox did updates on my laptop yesterday or the day before, and I'm wondering if that could be part of the problem. Does either of you know if there's a simple way to return to or reset the Firefox built-in default viewer? Perhaps that's what I just tried with Pkshadow's suggestion above?
Obviously, I'm not Tech savvy! The only thing that I changed a few days ago were my security settings on Firefox to try to prevent sites from tracking me all over the Internet.
I undid those security changes today, but it didn't fix the PDF viewing problem. I'm wondering if Firefox updates could possibly have messed something up, but if so, I'm sure there would be other users having the same problem.
