Firefox tries to save PDF files instead of opening

Posted

When I click on PDF links Firefox tries to save them instead of opening them. This is so even though in "Options" under "Applications" I have all Adobe files set to "Use Adobe Reader".

Chosen solution

You get the "Open/Save/Cancel" dialog, same as if you selected "Always Ask"?

When Firefox no longer responds to changes in the Application preferences, you sometimes need to reset those preferences, which involves deleting a settings file. This article has the steps for that under the heading "Reset download actions for all file types":

Thanks, resetting seems to have done the trick.
