I tried opening a pdf file and I set it to use always and firefox which did not work, I was wondering how to undo that and what I should use to open pdf files in the future?

I was attempting to open a document from a frequently used site, I had never been on, on my new mac however. I attempted to open the pdf file and was given the option of which program to use to open it, I mistakenly clicked use always and firefox as the program with which to open pdf files. I do not know how to undo this or what I should do in the future to access the pdf files.

Hope that helps.
