What can I do to rectify the situation in which Firefox will not open pdf files in the browser, even though I have already used all the help suggestions to no avail?

I have tried everything Mozilla has suggested. Still when I click on a pdf, I get the message that the browser cannot open a pdf. I have gone through the help protocol, and it does not work.

I have uninstalled Firefox and reinstalled it, and still not able to open pdf files within the browser.

What else do I do, except go to IE or Chrome and just leave Firefox completely???

A possible cause is the presence of a PDF plugin from an older Adobe Reader plugin in the plugins folder in the Firefox program folder. See Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems
