I installed cy10.0.0, it works fine with Chrome and Edge browsers. But when selecting Firefox and browser, it doesn't connect to it. Error: "Cypress failed to make a connection to Firefox. This usually indicates there was a problem opening the Firefox browser." The automation client disconnected. Cannot continue running tests. What I observed is a Firefox browser is opened but not connected. Then I have to manually paste the URL: http://localhost:60885/__/#/specs to the Firefox browser.

There's a github issue related to this, if there's any info you would like to add: https://github.com/cypress-io/cypress/issues/22086 Manually pasting the URL seems like a creative solution!
