File Associations Keep Changing

I have a problem where some of my file association keep changing the default program, whenever they feel like it. This is mainly happening with PDF and JPEG files opening in Adobe Software, when the default is set to Preview and always has been.

1. I have not updated any software recently nor I did change these associations to begin with

2. I have changed these via Get Info and checked "Always Open With"

3. I have changed these via OPT + RIGHT CLICK "Always Open With"

I am on OS X 10.11.6

Thanks so much for all of your help though!

Hope everyone can resolve this. Been a Firefox user for years.

I still am going to use Firefox. I just won't download anything with it. 😎

I also have this problem. High Sierra with Firefox Quantum installed.

JPG files open in Preview. Want to open in Photoshop by default. Photoshop not listed in Get Info..have to choose Other.

Just to check back in on this, I haven't had the issue since deleting firefox last week. It's been hard to not use firefox, but having this issue not come up really has improved my workflow :-)
