User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:52.0) Gecko/20100101 Firefox/52.0 Build ID: 20170323105023 Steps to reproduce: I updated to Firefox 52.0.2 (32-bit) and lose the opportunity to open embedded PDFs into the browser using Adobe Reader plugin. Actual results: Cannot open PDF file embedded into the browser using Adobe Reader plugin. Now PDF file is downloaded and saved - then opened in Adobe Reader Application... The default PDF viewer does not allow to fill a PDF form and post this form (through script - embedded into the PDF file) to the server into the browser's established session, so I used the Adobe Reader plugin, but no more have this opportunity. Expected results: To have the opportunity to open a PDF form, fill it and post the form to the server into browser's session... No matter whether using Adobe Reader Plugin or not...
I understood the situation: Java, Silverlight, Adobe Acrobat and other plugins no longer work... And the only opportunity is to use Firefox Extended Support Release till early 2018 The problem is that you do not give an opportunity for these plugins. For example your PDF viewer do not give the opportunity to fill PDF forms. Another problem is that I use a site where can receive information after signing with a Java. What's your solution? To stop using this site or to migrate to another browser? Let me guess... Probably I have to stop using Firefox... Probably many others like me too...

Not related to PDF Viewer, but to NPAPI plugins not allowed anymore. ESR 52 supports NPAPI plugins until Sept. 2017, you can switch to this version. Another temporary workaround is to add the boolean plugin.load_flash_only=false in about:config (and maybe delete the cache file pluginreg.dat in the profile). Some browsers like Chrome have stopped supporting plugins too.

And PDF forms will be probably never implemented, because the specs are not standard, only Adobe Reader supports filing PDFs all vendors don't.
