I find it more convenient to open pdf files in the browser, like I used to do in windows, instead of downloading them. Now, using safari or firefox, a window appears whenever I click on a pdf file link asking me if either I want to save it or open it using Preview. Preview is fine but I prefer Acrobat reader. So I tried to change the prefernces of both Preview and Acrobat reader so that pdf files are always opened using Acrobat, and made sure the same case applies when I open the files in a browser (this can be found in Acrobat reader preferences). However, I still have to save pdf files on my computer to open them with Acrobat, they forcefully open with Preview using a browser.
Ok, I looked in Safari's preferences and couldn't find something related
But on firefox I found "Download Actions", and could use "View & Edit Actions". A table of some file formats and their corresponding application is shown, but I can't do anything to the contents of this table. There is an "Add action" button but it's disabled.
Maco -- I've been trying to do this for months with no luck. I've changed settings on Firefox but it still wants to use Preview or save the pdf to the desktop. I think, but I'm not sure, that it has to do with Adobe not providing a plug-in for Mac OSX.
