Cypress: Opening Firefox on MacOS results in `Cannot read property 'on' of undefined` error
Current behavior:
cypress open
select Firefox 72
start test
Firefox window opens to a blank page
Error happens, then cypress exits with Firefox still open
TypeError: Cannot read property 'on' of undefined

Can you include the test code to run in Firefox to see this error please? This is likely relevant to the bug as just opening Cypress on our systems with any of our example and test repos does not produce this.

I also ran into this issue. Closing all instances of firefox and restarting the test runner fixed the issue for me

I face this issue as well. The ui test runner is crashed after starting the test. I also tried with an example spec files generated by Cypress and still found a crash.
OS: macOS 10.14.6 Mojave
Cypress: 4.0.0
Node: 12.15.0
Browser: Mozilla Firefox 72.0.2

I got the same error, too. Here's the snippet of the output after I picked Firefox 72. I got this output from DEBUG=* npx cypress open.

I got the same error even after switching repo and closing all instances of Firefox. Here's one of the repo: https://github.com/clarmso/xkcd-throw-calculator-cypress
Cypress 4.0.0
Mac OS Catalina Version 10.15.2
Firefox 72.0.2 (64-bit)

I am also seeing this error upon opening Firefox during cypress open on MacOS, so we do not need any more information provided since we can reproduce.
I am running cypress-example-kitchensink - this did NOT occur for me as an error during the prerelease as of this commit: https://github.com/cypress-io/cypress/pull/1359/commits/08873023c551f8fbcb6cfad9a09caf3fe1509037
I did not test run Firefox in MacOS after that commit, so it may be something involved with a commit after or with the merge/build.
Notably when I open Firefox, there is a blank new tab as the first tab and then this second tab shown below.
Full debug logs:
firefox-launch.log
Workaround
Firefox Developer Edition seems to open fine for me, so you could potentially download this release candidate to run in Firefox in the meantime. https://www.mozilla.org/firefox/developer/

I have the same issue on GitHub Actions but with Ubuntu 18.04.

Just to add further complication to the mix, I have just upgraded our works test suite to cypress 4.0.0 and on cypress open it detected my firefox 72.0.2 64bit installation, on mojave 10.15.2 and it works absolutely a-ok. (node v12.13.1)
Every test is passing correctly, with expection to those which required chromeWebSecurity to be set to false, which is as expected

Additional datapoint: I encountered the same crash as @fr0 when I trigger cypress and Firefox is already open. After closing Firefox, I was able to successfully run my test suite.
edit: Further Additional Context: as @jennifer-shehane first pointed out: with Developer Edition you can open multiple windows at the same time. So, it appears this bug is limited (for the time being) to Firefox 72.

Just tested this and I get the same issue with firefox open, prior to opening cypress.

@jennifer-shehane I just reproduce the error on Ubuntu 16.04, so the error isn't specific to Mac OS.

This error is easy to reproduce by opening Firefox in two side-by-side Cypress's in GUI mode. Since they share a profile, it will fail, because Firefox will not have opened Marionette at the right port.

The code for this is done in cypress-io/cypress#6370, but has yet to be released.
We'll update this issue and reference the changelog when it's released.
