I'm facing an error while running tests of an react app with testing-library and cypress. Tests running on unit test and e2e chrome is fine till it running on e2e firefox.
I haven't used firefox before, i was installed firefox from here to run the test on demand, but it doesn't seem to work. I've tried searching the internet for errors but couldn't find any similar articles.
Any ideas on how to solve this are welcome. Thank you all for reading.

Cypress failed to make a connection to Firefox.
This usually indicates there was a problem opening the Firefox browser.

CodePudding user response：
There's an open issue here "Still waiting to connect to Firefox" issue in Cypress 10.0.2 on Windows #22086.
I can confirm the same occurs on my system.
But, I can use Firefox nightly
script
"test:e2e:firefox": "npx cypress run --headless --browser firefox:nightly",
These are the paths used for Firefox (under C:/Program Files)
stable: getFirefoxPaths('Mozilla Firefox'),
dev: getFirefoxPaths('Firefox Developer Edition'),
nightly: getFirefoxPaths('Firefox Nightly'),
I have both "stable" (specified by --browser firefox) and "nightly" (specified by --browser firefox:nightly) but I can't see why "stable" isn't firing up. It seems to be installed the same way a "nightly"
