Analysis

This system test was added to detect regressions due to a fix implemented for #5016. This test exhibits flake in Firefox, even when run against commits prior to the 5016 fix. The test that should be succeeding but fails in this system test clicks an anchor with target="_blank" and takes a screenshot of that anchor: https://github.com/cypress-io/cypress/blob/develop/system-tests/projects/config-screenshot-on-failure-enabled/cypress/e2e/issue-5016.cy.js

Cypress Version

13.6.7

Other

For now, we are disabling Firefox on this system test. This is likely indicative of .screenshot() intermittently failing with a timeout error in Firefox when the main Cypress tab is not focused.

This issue has not had any activity in 180 days. Cypress evolves quickly and the reported behavior should be tested on the latest version of Cypress to verify the behavior is still occurring. It will be closed in 14 days if no updates are provided.
