PDFs are not opening in Firefox

Hi everyone,

I use Firefox' built-in PDF reader to open all of my PDFs stored on my computer, but they suddenly stopped working. I open a PDF in Firefox and it brings up the "What should Firefox do with this file?" window and prompts me to either open it or save it. I try to open it but it brings up a new empty tab along with the same window prompting me to open or save it. This goes on and on, and it happens with other PDFs I download.

Is there a way to fix this? My application preferences are set to the default.

Thanks
