How do I get PDF listed in "Options">"applications"? I want to stop FF pdf reader and use Tracker pdf viewer.

I use FF 21.0 on a desktop ruinning Windows 7-64.

I want to stop the FF pdf viewer and use my Tracker pdf viewer, like i did before FF added pdf viewing. I tried going to options>applications but there is no listed pdf viewing line other than one line for Tracker. I believe I need a line that mentions pdf files in the left column and then a listing in the right column allowing me to use Tracker (hopefully as a plugin).

I'm lost at this point and wish I had the older FF that didn't have pdf viewing built in.

Help please.

Files always need to be downloaded if you want to open them.
Some are saved in the disk cache (e.g. Flash) and others in the temp folder (the ones past to other external programs and some plugins).

There has been a change in where Firefox searches for plugins and the plugins folder in the Firefox program folder is no longer scanned for plugins, so Firefox won't find them anymore if they are installed in the plugins folder instead of the "browser\plugins" folder that Firefox now scans.

You can set the plugins.load_appdir_plugins pref to true on the about:config page to make Firefox scan the "<install>/plugins/" directory for plugins like the WMP plugin (np-mswmp.dll).

You can alternatively move plugins from "<install directory>\plugins\" to "<install directory>\browser\plugins\" to make Firefox find them again.


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.

This sounds interesting but it doesn't say anything about how I can add PDF in the left column where file types are listed. My list is rather short and doesn't change even when I delete "mimetypws.rdf" and then reboot to re-create that file.

Without pdf in the left column I cannot even try to associate it with Adobe, Tracker, or whatever.

This started when FF added its own pdf viewer that causes my pdf files to have the top of them distorted.

This is no help to me.

The link tells me how to access "Portable Document Format (PDF)" in the left column. I have stated that "Portable Document Format (PDF)" does NOT exist in my available list. If it did, I'd probably be able to solve my problem.

Thanks

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

You can use this button to go to the Firefox profile folder:

Yes, I have already done this and the new file created is also lacking the "Portable Document Format (PDF)" entry.

I can't believe it is so difficult, I must be missing something here.

Thanks.

I'm not sure why it isn't populating. Do you have a PDF reader application installed as an external application?

If you would consider some manual file surgery, you could try adding a couple of lines to that mimeTypes.rdf file. If it gets hopelessly messed up, you can again delete it and have Firefox generate a new one.

If you open mimeTypes.rdf in a text editor (preferably something smarter than Notepad because Notepad cannot understand the line breaks), and search for PDF, you can see whether you have these. (Note: on the first one, you would add the middle line to your existing list and not create a duplicate list of mimetypes.)

New info:

I have set "pdfjs.disabled pref to true" and now the FF pdf viewer does not operate (as far as I can tell so far).

My Tracker pdf viewer does work (good) but all pdf files I select are also downloaded (bad) before I see them.

Is there a way to have FF show me the pdf files opened, but not downloaded to my computer?

Thanks

Hi fungusEYE, you wrote:

PDF files will always be downloaded to the cache or a temp folder even when viewed in the browser. Is that what you meant, or is the PDF launching externally?
