When I double-click the Mozilla Firefox icon on my desktop, a pop-up appears saying "Couldn't load XPCOM"

When I click the START button click on CONTROL PANEL click on PROGRAMS (uninstall a program) select Mozilla Firefox 43.0.1 (x86-en-US) and click on UNINSTALL nothing happens.

Downloading Firefox from your website is unsuccessful.

Opening the HELPER.EXT (in C:\Program Files (x86)\Mozilla Firefox\uninstall) doesn't work either.

Download Firefox For All languages And Systems {web link} Save the file. Then;

Using your file browser, open the Programs Folder on your computer.

Windows: C:\Program Files C:\Program Files (x86) Mac: Open the "Applications" folder. Linux: Check your user manual.


Look for, and rename any Mozilla or Firefox folders by adding .old to them.

After rebooting the computer, run a registry scanner. Then run the installer. If all goes well, remove the OLD folders when you are done.

If the system has trouble doing this, Start your Computer in safe mode with networking. Then do the above.
