Old version failed to update, downloaded new version did not update existing but create additional firefox
My 89 version failed to update, when I downloaded and installed a new version of firefox, it did not update the old version, instead it install another firefox into my windows 10. Now I got two firefox in my computer, the old one with all my customisation and a new one which are clueless about the old one. How do I resolve this?

Hi yappyml,
Uninstall the newer one, and in older one,
- Click the menu button, click Help and select About Firefox.
- The About Mozilla Firefox window opens. Firefox will check for updates and download them automatically.
- When the download is complete, click Restart to update Firefox.
Note: Update settings can be changed in Firefox Settings .
Click the menu button and select Settings.
In the General panel, go to the Firefox Updates section.
