Pdf file is downloading as html?

So I uninstalled Firefox from new computer. Then completely emptied!!! Reinstalled Firefox and problem disappeared I only copied bookmarks from old computer, not all profile. Additional link added by a moderator.

The solution above is not a general solution for everyone. My post under includes an explanation and potentially useful information including links to workarounds. I located the application data referred to in the solution with difficulty; I deleted the profile files as recommended and reinstalled Firefox; but my pdf files were still labeled as type: Firefox html document.

My pdf files still appeared as Firefox html documents and would open firefox every time I clicked on them. Then I right clicked on one of these firefox html documents and chose "open with Adobe reader".

That particular file, as well as every other firefox html document on my computer changed to Adobe pdf with the Adobe icon. This thread is about Firefox registering as the default handler for PDF files if none such application is already registered. This has nothing to do with the Firefox profile folder as this only involves one or more registry keys.

Please don't make up headers and send them. Could you update your answer. Be careful when using this code verbatim, though. This code is likely dangerous in another way. Could be used by an attacker to attempt to scan your internal network for exposed PDF files. Not to mention how easy it would be to bypass any "sanity checks" you think you'll be doing to the "file" parameter.
