Hey guys

Today I got so annyed by firefox’s default behaviour of downloading each and every PDF file to my disk that I went searching for a solution until I had the problem fixed. And it seems like I have finally found it. I have linked the solution but here is the fix in short:

  1. go to about:config
  2. change browser.download.open_pdf_attachments_inline to true

Thank you jscher2000 for the solution!
