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).

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.

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.

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

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