cypress test not run on Firefox but works fine with Chrome and Edge

[Rajesh-Kodandam]

I have windows 10 and cypress: 7.4.0 and Firefox78.11.0

When I run tests in Chrome 91, Edge 91 and Electron 89 works as expected. But same test run in Firefox 78, received an error message "Whoops, we can't run your tests. This browser was not launched through Cypress. Tests cannot run."

Also I see that in Firefox browser says that Cypress is currently running and automating your browser.

Any help much appreciated. Thank you
