How do I reset how I want to view a download? Firefox is now immediately downloading PDFs without asking me my preference.

I have been using Firefox and it used to ask me if I wanted to save a download or open it. Now, when it is a PDF it automatically downloads. I don't need all of these downloads on my computer. When I go to Options, I have checked the box that says "Always Ask Me Where to Save Files". I only want to open downloads, not save them.

Deleting the mimeTypes.rdf will reset all download actions to the default settings.

Type about:support in the address bar and press enter.

Under the page logo on the left side you will see Application Basics. Under this find Profile Folder. To it’s right press the button Show Folder. This will open your file browser to the current Firefox profile. Now Close Firefox.

Locate the file. Then rename or delete it. Restart Firefox.
