Previously, when I downloaded a pdf file and I clicked open, I used to get small pop up window asking what app I want to use to open the pdf file with. Now, it just opens in Firefox. I don't want to view the pdf in Firefox. I can go to the files folder, find the file that j downloaded, select the three dots options menu and select open with. But thats too convoluted. I would like the previous functionality back of whenever I click open on a download pdf file, it asks me how I want to open it instead of directly opening it in Firefox.

Thanks for your help!
