Use when reviewing CI coverage, automated checks, or test strategy related to Test across all major browsers. Focus on whether the rule is continuously verified, not just documented.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Test across all major browsers Users access your site from different browsers, each with unique rendering engines. Without cross-browser testing, a significant portion of users may experience broken layouts, missing features, or complete failures. ## Quick Reference - Test on Chrome, Firefox, Safari, and Edge at minimum - Use automated tools like Playwright or BrowserStack for CI testing - Check CSS features with caniuse.com before using - Test on both desktop and mobile versions of browsers - Document and gracefully handle unsupported features ## Check Verify that this website works correctly across major browsers (Chrome, Firefox, Safari, Edge). ## Fix Fix browser-specific issues and ensure consistent experience across different browsers. ## Explain Explain the importance of testing across browsers to ensure all users have a good experience. ## Code Review Review tests, CI workflows, and enforcement points related to Test across all major browsers. Flag exact gaps where the rule is not automatically verified or where failures do not block regressions. --- For full implementation details, code examples, and framework-specific guidance, see `references/rule.md`. …

How to install
mdr add thedaviddias/front-end-checklist/cross-browser-testing@sha256:fee2517ab05ef880The line at the top of this page pins the label git:20261004.4b0ddb9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
