I started getting the message that an associated helper file can't be found when I try to open a pdf. I found instructions that say I should go to tools/options, select content, and then in the file types section select manage. But there IS no file types section under content. Where has the new Firefox moved the file types section--I can't find it anywhere.

Hello,

In your Options dialog go to the Applications tab. You can manage your file associations there.

Note that if you are still having problems with your file associations, you may have a corrupt mimetypes.rdf file. You can go to your profile to rename it to mimetypes.rdf-old or something so that Firefox can rebuild it and reset all your associations to default.

To access your Profile, go to the about:support page, or:

  • Help (or New Fx Menu > Help-29) > Troubleshooting Information

And click Show Folder.
