When i try to print a pdf file trough gmail trough the preview window of the pdf, instead of printing it downloads a pdf file with a very long name (example of real filename: ACFrOgAcZiEDMs3JEBQmIpDaAGloJLSCzqQnju2ahdPe2m6v--kxq5xmHsQ3_OiYnd1RVZ5fR46JDQDXONNeSB2VeMNtaXzW3U7wPL1OahSYDRH2GxIrcVbFC68h2sFQPuJpmH_Id0M_oYukAKAjAq4dkn6a4oiPfF9Un5V3Cw==) which looks like javascript to me. when I open the pdf file (my default viewer is adobe acrobat) it opens the file instantly with the print dialog open. I have tried about:config booleans regarding opening and downloading pdfs I have tried checking firefox settings and there is only "always ask", "save file" and "adobe acrobat" options and no "open in firefox" option and when i make it "always ask" and choose "open in firefox" from that option it just repeatedly gives me the "ask" window on new tabs each time i click ok. I have also checked popups for gmail, they were not blocked so i have disabled and re-unblocked popups from gmail site it works on every other site but gmail which is the main place i need to print files from.
