pdf - Firefox Links to local or network pages do not work

Question

I have a .asp application where image files (.PDF) are stored in a directory (fed by a copier/scanner). The created file names are stored in a database table. When a query is launched from the web page a link to the file is created. When clicked the image should be displayed. This functionality works 100% in Internet Explorer. No such luck in Firefox (and I have some Firefox users). The created hyperlink looks like this file://Server/Scanner/XYZ.pdf

The Firefox helps suggest the reason is this:

Links to local or network pages do not work. As a security precaution, Firefox forbids sites on the Internet to link to files that are stored in your local computing environment. These files may include files on your computer, mapped network drives, and UNC network paths

None of the suggestions for a workaround seem to work (or I am not understanding the steps to create the image display) Any Suggestions?

Answer 1

This is the default Firefox behavior designed for security .The assumption is probably that most web sites don't know what and where are you local files (including UNC paths).

This could be turned off in firefox:

• type "about:config" in the address bar and accept "i'll be careful"
• find "security.checkloaduri" in older versions or "security.fileuri.strict_origin_policy" in newer versions of firefox and change the value to "false"
• restart firefox

That should do it for you. You have more information here:
