Hello, Sometime between Friday and today (Monday) Firefox has "hijacked" all of my pdf documents. I didn't ask for this and don't what this. I did find the setting that controls how Firefox handles downloads, it was set for open in Firefox, I switched to back always ask and restarted my laptop. All my existing files are still saved as Firefox HTML Documents. Additionally, when printing from the web files are still saving/printing as the Firefox HTML docs. How can I fix this?

Thank You, Kathy

Hello, I continued to poke around for a fix & I found it, doesn't explain why this happened but this is what I did. Right click on any of the Firefox HTML docs, select open with, select Choose default program, select Adobe Acrobat then check box to apply this to all files.
