Without my doing anything, firefox has decided to download pdf files in its own html. I have changed the default to adobe rather than ask. When I open the downloaded file in adobe it comes down as an adobe file, I tell it to save as an adobe pdf, but it appears in file manager and then opens in firefox html. Worse, it, whatever it is, has gone into file manager and changed adobe pdf files, some of which have been sitting on my hard drive for some years, into firefox html files. How do I rectify this please?

Hi, as I understand, the icon and the filetype description has been unexpectedly changed to "Firefox HTML document", but this is not a pdf conversion. It's still the same intact PDF. Just set the default pdf reader (in OS settings) back to Acrobat and everything will back to normal.

Thank you. I've tried that (windows 10) - it shows adobe is there as default app, but it's still storing in firefox. This means I have to tell it to open the file it in adobe, but that's an extra step I shouldn't be having to make.

Could you double-check your preference for PDF files on the Settings page. This article has the steps: View PDF files using Firefox’s built-in viewer.

Does this only work with newly downloaded PDF files? I changed the setting but when I open click on the document it still opens in FIrefox. The extension for this file is Firefox PDF Document (.pdf). Even if I open the document in Adobe and save it as an Adobe PDF it still opens in FIrefox when I click on it.

How can the Firefox Adobe feature be disabled?

ADDENDUM: My existing PDF files have been changed to Firefox PDF. This is most annoying.

Are you running Windows 10-11? Go to the system search bar (could be on the Taskbar, or Start menu) and enter default apps and click Default apps to call up the system settings panel. Toward the bottom, click Choose apps by file type. Wait for Windows to load this list... patiently... Scroll down to .pdf and click whatever program is shown as the default program for opening .pdf files. Select your preferred program from the list.

Switch over to a regular File Explorer window and see whether that fixed the problem.

Thank you that worked perfectly.
