Firefox has been installed and working on my pc computer for several years. Today the browser will not open. The only program file shown on install or uninstall is firefox.exe. When I click on the start icon or try to open it from programs I get an error message. It says firefox.exe-bad image. error status- 0xc000012f . Not designed to run on windows or it contains an error. The Firefox Browser on my computer contains a lot of information. The user name is dltpm3@aol.com How can I restore it? Maybe with MS Edge? Thanks for suggestions. Peter M.
