Hi, Firefox has automatically been "asking me" if I want to save the pdf document instead of showing them in the browser. I have update 22. I have tried to look for the pdf options under the options>applications settings and it doesn't even show up! Is this because I updated? I updated on July 4th and didn't need a pdf until now and this problem showed up. Before, I did not have this problem. PDFs were opening on the browser and I had that pdf option under the application's list. So I don't know what to do since I don't even have that option on here. What should I do?

Current Firefox versions have enabled a built-in PDF Viewer that doesn't have all features that other PDF readers like the Adobe Reader have or may not function properly otherwise.

You can change the action for Portable Document Format (PDF) from Preview in Firefox to use another application like the Adobe Reader or set to Always Ask in "Firefox > Options/Preferences > Applications".

You can set the pdfjs.disabled pref to true on the about:config page to disable the build-in PDF viewer.

You can check the value of the plugin.disable_full_page_plugin_for_types pref on the about:config page and remove the application/pdf part if present or reset the pref to the default via the right-click context menu.

You can delete the mimeTypes.rdf file in the Firefox profile folder to reset all file actions.

Hi thank you for taking the time to reply.

"You can change the action for Portable Document Format (PDF) from Preview in Firefox to use another application like the Adobe Reader"

Yes, I have Adobe Reader installed and that's my preffered option. I have recently and manually uninstalled Adobe reader,Reinstalled it again, restarted my computer, and I am still having the same problem. I cannot see the option to preview the pdfs in firefox using adobe. It either uses the the Firefox pdf reader Zeon? or the other option is to Always ask me to download it to my desktop.

I have attached what I see, maybe you can help me based on that. It seems the plugins work well (Figure 2) but only the pdf plugin for adobe to be previewed in firefox is missing (Figure1).

Also, I attempted to re-initialize the plugin database but it still gives me the same option as always.


"You can set the pdfjs.disabled pref to true on the about:config page to disable the build-in PDF viewer."

No, if I set it to "true" then the pdf option under applications disappears. So I have kept it as false. (Figure 3 shows that it goes missing, not the same as in Figure 1)
