Registry Editor (regedit.exe) is a Windows tool to view and edit the Windows Registry — a hierarchical database that stores low-level settings for the OS and applications.

When you right-click a file and see multiple Firefox entries, those are stored in the Registry under:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.pdf\OpenWithList

Export this key before cleaning it out, then delete the entries you don’t want. If something breaks, merge your backup .reg file.
