Windows 10: Issues reinstalling Firefox

Firefox is my main browser, so I have almost all my favorites saved on it (which I saved prior to this). Since I was unable to print from Firefox, I decided to just do a clean install. So, after uninstalling Firefox, during the reinstallation, I have received this annoying message that says, "Couldn't load XPCOM." As a result, I cannot pull up Firefox.

firefox issues after microsoft 10 upgrade

Hi Steve,

If you're having issues with Firefox after updating your operating system, we recommend that you perform a clean reinstall of the program. This process does not remove your Firefox profile data (such as bookmarks and passwords), since the information is
stored in a different location. To do a clean reinstall of Firefox, please follow these steps:

• Download the latest Desktop version of Firefox by visiting their official website and save the setup file to your computer.
• Completely remove the application from the system by accessing Programs and Features through control panel then select Firefox and uninstall the program.
• Delete the Firefox installation folder, which is located in one of these locations, by default:
  
  C:\Program Files\Mozilla Firefox
  
  C:\Program Files (x86)\Mozilla Firefox
• Proceed with the installation. Double-click the downloaded setup file and go through the steps of the installation wizard. Once the wizard is finished, choose to directly open Firefox after clicking the finish button.

Give us an update with the outcome.
