Hi!

When going to Option>Applications and searching for "pdf" 2 options come up in the list: 1 - pdf. 2 - portable document format. For "portable document format" I can choose "preview in Firefox", but for "pdf" the preview option does not exist (I can just "save" or "alway ask" [and that just gives option to save or open with TWINUI]).

I tried to erase the "mimeTypes.rdf" and then "pdf" disappeared from the list all together leaving just the "portable document format" in the list. All pdf's opened in FF just like I wanted! But that only worked for a short while and "pdf" appeared again in the list with no preview option.

I use FF28 and win8.1 (comes with TWINUI to view pdf). I didnt want to install more programs like adobe, so I want to open pdf files that are on my computer in FF.

Thanks!

You can only select "Preview in Firefox" if the MIME type is "application/pdf".
If you have a file action for another MIME type then that content type is treated differently.

Yep and you can manage the other file types in the Application settings in Preference/Options as you have done before.

There is also a nice add on for previewing both types, I think. https://addons.mozilla.org/en-US/fire.../?src=search
