'Firefox' was not found in cypress/included:5.0.0

[liunate]

Use container cypress/included:5.0.0 at github actions shows firefox was not found or unsupported error in run log:

Run yarn test-cypress-ci
  yarn test-cypress-ci
  shell: sh -e {0}
  env:
    CYPRESS_BROWSER: firefox
...
yarn run v1.22.4
$ start-server-and-test start 9966 'cypress run --browser $CYPRESS_BROWSER --headless'
...
Can't run because you've entered an invalid browser name.
Browser: 'firefox' was not found on your system or is not supported by Cypress.

p.s. Environment var CYPRESS_BROWSER is substituted in npm script test-cypress-ci:
"test-cypress-ci": "start-server-and-test start 9966 'cypress run --browser $CYPRESS_BROWSER --headless'"

Full log can be viewed at ci job log

The git workflow file is here

I also tried reverting to previous image such as 4.12.1 but it shows the same error

Strangely the very same image cypress/included:5.0.0 works perfectly at local with command:

docker run -it -v $PWD:/e2e -w /e2e -e CYPRESS_BROWSER=firefox --entrypoint=yarn cypress/included:5.0.0 test-cypress-ci

FYI the package.json scripts is:

"test-cypress-ci": "start-server-and-test start 9966 'cypress run --browser $CYPRESS_BROWSER --headless'",

Also seeing this on cypress/browsers:node12.14.1-chrome85-ff81

Same problem with cypress/browsers:node12.13.0-chrome78-ff70

@liunate since you run on GitHub Actions, why don't you use https://github.com/cypress-io/github-action ? Then 90% of the workflow yml file is probably unnecessary :)

[bahmutov]

Could you try cypress/included:6.0.0?

[paolocattani]

I solved the problem setting user as 1001 ( I'm using this image inside GitHub pipeline )

container:
      image: cypress/browsers:node14.15.0-chrome86-ff82
      options: --user 1001 --shm-size=2g

Nice, but @paolocattani I would suggest simply running the Cypress tests using Firefox on GitHub Actions without Docker - because FF82 is pre-installed there.

@bahmutov I just follow these instructions :D https://github.com/cypress-io/github-action#browser

btw thanks for your advice, take a look to the pipeline if you want
