My issue started with downloading the most current Firefox. Firefox opens multiple empty tabs (20 -30 or more) every time I use adobe reader. I changed the action for a content type to show adobe reader. It was showing open the file in adobe in Firefox. I uninstalled and reinstalled Firefox twice and this did not work. I uninstalled Adobe Reader and Air but could not uninstall Adobe Flash Player because of a conflicting Application with Firefox. I then uninstalled Firefox and was able to uninstall Adobe Flash Player. I reinstalled Adobe Reader only and then Firefox. I no longer have multiple empty tabs opening up but each time I open a pdf file, Firefox has to open as well. I am operating on Windows 7 Home edition. Can some one help this is a nuisance.

Thank you, Steve Zalkin

Poen the pdf file in firefox first then choose open another way OR select the pdf file any one and make adobe reader as its default viewer. Update the reader.

Try to rename (or delete) the mimeTypes.rdf file in the Firefox profile folder to reset all file actions.

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 if you want to display PDF documents in Firefox with another application (i.e. not the built-in PDF Viewer).
