Still cannot open Firefox in 4.0.1 on MacOS

[jennifer-shehane]

Current behavior:

I downloaded 4.0.1. Initially I got what looked like the weird new tab issue like the issue before (without the on error) :

So then I just closed the browser and then I got this error.

Cypress could not connect to Firefox.

An unexpected error was received from Marionette connection:

Error: cannot open socket

To avoid this error, ensure sure that there are no other instances of Firefox launched by Cypress running.

So I'm like...ok...I hit 'Try Again', it loads the specs back up, but when I click the spec file I get this popup.

If I click Quit, basically nothing happens, so then I was like, ok...let's create a new profile I guess. So now it launching Cypress with the 'orange striped bar' and this displaying in the second tab.

Desired behavior:

Can y'all please verify that Firefox runs on my machine before the next release 😅 I can't debug other people's issues without being able to run Firefox.

Test code to reproduce

cypress open or cypress run on MacOS Mojave 10.14.6
