After Firefox updated to version 19, when I tried to view a pdf file, the file appeared in a strange new viewer. Seemed to work OK, but I was concerned (didn't know that it is apparently a new feature of FF 19), and wanted the Adobe viewer back.
After a few minutes of viewing in the FF pdf viewer, a message appeared that said something like-- This viewer may not be displaying the document correctly. Would you like to use Adobe Acrobat instead?-- I clicked yes.
Now, when I click a link for a pdf file, it will either open automatically in Adobe Acrobat (windows application, not viewer within FF), or I'll get a dialog that asks whether I want to save the file or use Adobe Acrobat to open it.
I have followed the instructions here:
Including: http://support.mozilla.org/en-US/kb/view-pdf-files-firefox-without-downloading-them
Delete the mimetypes.rdf file
Delete the pluginreg.dat file
Let me know if you think I've missed any info that would be helpful. Now that I know the new PDF viewer is FF native, I wouldn't mind trying it out.
Thanks!

repair of Adobe Acrobat
If I start IE and click a pdf link within IE, I can view a PDF file within IE, but who wants IE?

philipp 5 years ago hello, if you want to switch back to the plugin you've used before to view pdfs just go to firefox options > applications & define the default action for the portable document format (pdf).

Who_Knew 5 years ago Hi madperson,
Thanks, but setting the options to define the default action for the portable document format is among the things listed that I have already tried. Modifying the default action only lets me select whether I save the file or open it with Adobe Reader (not in browser). Selecting the plugin doesn't seem to make the plugin work.

philipp 5 years ago ok, in this case it's maybe also necessary to totally switch off the inbuilt pdf veiere - enter about:config into the firefox location bar (confirm the info message in case it shows up) & search for the preference named pdfjs.disabled. double-click it and change its value to true.

Who_Knew 5 years ago Hi madperson,
It seems like there is some progress. After setting pdfjs.disabled to true, when I click on a pdf link, it still only asks me if I want to open the file with (application list) or save the file. However, when I look at the options dialog>applications, the selection for pdf documents changed from use plugin to use Adobe Acrobat Reader (not plugin). I scrolled through the selection list, but the Adobe plugin was not listed. However, when I look at the add-ons screen, the Adobe Acrobat Reader plugin is listed at the top. So, it seems like the plugin is installed, but firefox doesn't know it's there...somehow.
How do I uninstall the Adobe Acrobat Reader plugin and re-install? Can I just do that? Or, do I need to uninstall/reinstall the entire Adobe Acrobat Reader application?
Thanks

Who_Knew 5 years ago OK, I guess I'll try an uninstall-reinstall of FF and Adobe and any other PDF readers
