Will Firefox 100 work on Windows 7?


Firefox 100 is fast approaching, and this version of the browser should still work on an unsupported Windows 7 system. However, if you want to use the program, you will have to install a special patch. Without it, Firefox 100 won’t work on Windows 7 computers.

Mozilla plans to release Firefox 100 next month. This Web browser will still offer support for Windows 7, which Microsoft killed more than two years ago. However, the application will require a special update. What is this patch?

The Windows 7 patch mentioned is KB4474419. It will be required because Firefox 100 introduces a change in code signing and will switch to SHA-256, which the aforementioned patch adds to the old windows. Installing it will be necessary, otherwise the Mozilla browser will refuse to work.
