I now think this is also happening with the postage purchase program at usps.com - I first thought they were not compatible with mac, which is not unusual - but now I think it is firefox. Reproducible: Always Steps to Reproduce: 1. go to website http://www.irs.gov/pub/irs-pdf/f1120.pdf 2. hit forms and publications 3. try to open i.e. form 1120 or 1040 - a screen opens but it is blank. do the same in safari and it is fine. I have used firefox for a few years to obtain these documents and it has never failed before Actual Results: a screen opens but it is blank and it says "done" in the bottom left corner Expected Results: usually a screen opens as a pdf -if it is fill-in-able or a screen opens and asks if you want to open file with adobe or save it to disk. I have used http://www.irs.gov/pub/irs-pdf/f1120.pdf phoenix.gov - production manual and usps.com to open pdfs for at least two or three years. This does not happen in safari (FYI I do not like using safari) Thank you!!
The current version of Adobe Reader doesn't support Firefox running on Mac OS X. Please see the Firefox Support issue link below: http://support.mozilla.com/en-US/kb/Using+the+Adobe+Reader+plugin+with+Firefox?s=PDF If you wish to open a PDF on Firefox browsers, you have to install the PDF Browser Plugin 2.3.1 to your System. It supports Intel or PPC Mac with Mac OS 10.4 - 10.5 and Firefox 3.0.x (also Firefox 3.5.x). http://www.schubert-it.com/pluginpdf/ Otherwise, install the Firefox PDF Plugin for Mac OS X from AMO. https://addons.mozilla.org/ja/firefox/addon/7518
3.5 version is not supported anymore, plus nothing that can be done by Firefox as this is an issue that has to be solved by Adobe, or can be worked around by the instructions given in comment 1. Closing as INVALID.
