I have my settings set to "Always Ask" what to do with a PDF file. This is how I want it to work. I want to be able to choose what to do with a PDF file every single time. However, it's a HUGE problem that if I select "Open in browser / Open with Firefox", the window displays a temp file URL (file:///C:/Users/XXX/AppData/Local/Temp/XXX.pdf) instead of the PDF's actual URL. This is not okay!! When I choose to open a PDF file in the browser, the PDF's URL should appear in the address bar. I don't care if the file still goes to the temp folder -- the temp download is not my issue. When a PDF file is opened in the browser displaying a temp file URL, it's impossible to save the link to your Bookmarks -- you actually have to save the file!!! That is 100% the OPPOSITE of the intended behaviour! You shouldn't be forced to save a file to your computer when you could be saving a link to your Bookmarks! The other problem is of course that you can no longer copy or share the URL unless you go back to the first page where you clicked the link. Along the same lines, there are three reasons I don't want to set my PDF preferences to "Open in Firefox" by default. Firstly, I don't want to be forced to view a PDF if I know I just want to save it. Hence preferring to be asked every time. Secondly, and more importantly, I want to be able to choose to open the file in Acrobat without having to save it to my computer. Thirdly, the setting changes the way Gmail attachments can be opened, where clicking the Download button no longer downloads, but opens in a new tab! A download button shouldn't be treated the same way as a URL link!! When people click download, they expect to open the file in an external app, or to save it -- NOT to open it in a new tab. Overall, it's a ridiculous way to set up PDF viewing, and needs to be fixed. I would appreciate suggestions until Firefox improves the way it works with PDFs.
