Cannot view pdfs in Firefox. - Browser doesn't recognize them as pdfs
I cannot view pdfs in Firefox. I checked the Applications section of FIrefox preferences and instead of saying "Adobe Acrobat PDF document"- it says "Adobe Acrobat FDF document. I am guessing that the browser does not recognize pdfs because the content type is incorrect.
I am using a Mac running OSX 10.8.2 and Firefox 17.0, however I have had this problem for several months and several earlier versions of Firefox as well. Please fix this issue. According to the help center forums, I am not alone with this issue.

Hi tdeebulling, try to delete the mimeTypes.rdf file in profile folder and see if this solve the issue.
thank you
You can disable the Adobe Reader plugin in Firefox (Tools > Add-ons > Plugins) and use the external Adobe Reader application or Preview application instead.
- Firefox > Preferences > Applications > Adobe PDF document : Use Adobe Reader
Thank you for your suggestion, but my preferences are already set to view using Adobe Reader.
I have deleted the file mentioned in your post and nothing changed. I think there is something wrong with the pdf preferences to begin with because under Content Type it says Adobe Acrobat FDF document instead of Adobe Acrobat PDF document. That is not something that I can change.
Thank you for your help. What I ended up having to do was to change the Action next to Adobe Acrobat FDF document to "Use Preview". Then again under the Preview.app Document under Content Type, I had to change that to Use Preview as well. It is now working. However, Firefox (Mozilla) needs to change the word FDF to PDF in their preferences file.
