@MikeMcC399 @willmsC here is the related issue to #31316. I am going to close #31316 as the provided solution is a non starter, but I would like to track the findings of the missing web extension install here.

@willmsC are you able to provide the details I asked for in #31316 (comment) on this issue instead?

Since Firefox 129, Chrome DevTools Protocol (CDP) has been deprecated in Firefox. In Firefox 135 and above, Cypress defaults to automating the Firefox browser with WebDriver BiDi. Cypress will no longer support CDP within Firefox in the future and is planned for removal in Cypress 15.

Cypress failed to make a connection to Firefox.

This usually indicates there was a problem opening the Firefox browser.

I took the liberty to cleanup the profile and prefs in the session Json to make the log more readable.

I also want to apologize for not being able to share more details about our test environment setup. However, if needed, I’m happy to check internally to see what additional information I can provide.

I could also imagine that it would help with my specific problem if one could set the path to the extension via environment. See also my last comment in #31316

This may not make any difference for troubleshooting, however Cypress officially supports only the latest 3 browser versions, which for Firefox would currently be

134, 135 and 136

See https://docs.cypress.io/app/references/migration-guide#Updated-Browser-Support

@willmsC do you have the cypress firefox logs as well printed from DEBUG=cypress:server:browsers:firefox,cypress-verbose:server:browsers:firefox? I'm curious what install path we are giving the extension. Are you unable to provide that?
