Opening pdf files opens a blank tab and downloads a copy of the pdf.

I've reinstalled Firefox, and it worked for a bit, but now it's doing this again. I have a few extensions installed, but the problem stays the same after disabling them. I have updated to version 69.0.3 (64-bit) and nothing changed.

This can happen if you have disabled the builtin PDF Viewer. You can check this in "Options/Preferences -> General -> Applications" PDF should be set to "Preview in Firefox".

Sounds that you selected Firefox as the application to open PDF files, you should never do this. You can check the action for Portable Document Format (PDF) in "Options/Preferences -> General -> Applications" and make sure it is set to "Preview in Firefox".

You get tabs opening endlessly if you select Firefox as the application to handle a file when you get an "Open with" dialog.

Thanks for getting back to me!

It seems the issue is solved by changing the settings towards your proposal, the strange thing remains settings never got changed by myself and things always worked, I do have a firefox update in suspicion causing the problem..
