Troubleshooting Multiple Firefox Installations on Windows 11: A Comprehensive Guide
Are you experiencing issues with multiple Firefox icons appearing on your Windows 11 taskbar, yet only seeing one entry in your Add/Remove Programs list? This is a common scenario that can cause confusion and concern about your system’s integrity. In this article, we’ll explore the possible causes, implications, and effective solutions to ensure your browser and system are functioning correctly.
Understanding the Issue
Many users have reported situations where Firefox appears to be installed multiple times on their Windows 11 computers. Typically, after reinstalling or updating Firefox, users notice:

-
Corrupted or Stale Registry Entries: Windows may retain outdated or duplicate entries in the registry, causing inconsistencies in the Programs & Features list.
