What?

Excludes the firefox project from the Playwright job's (e2e-playwright) test run in .github/workflows/end2end-test.yml on wp/6.2, alongside webkit (already excluded by the fix-playwright-noble-install layer). Also drops the now-unused libdbus-glib-1-2 system-package install step, since it existed solely to satisfy Firefox's one runtime dependency and Chromium needs nothing extra.

Why?

This branch is pinned to @playwright/test@1.30.0 (.nvmrc is Node 14, leaving no headroom to bump it the way branches with newer Node, e.g. wp/6.5/wp/6.6, already did). On this pinned version, every real run of the firefox project on the ubuntu-24.04 runner reliably crashes partway through with browserContext.newPage: Page closed, which then cascades identical Page closed failures through the rest of that worker's queued tests.

This is not test-content flakiness: playwright.config.ts already sets workers: 1/retries: 2, and every retry of every affected test fails with the exact same error, because the underlying Firefox browser process itself has died for the rest of the worker's run, not an individual test or page.

Confirmed reproducing identically, not a one-off:

• PR Repair wp/6.2 branch Actions: Use mariadb client instead of removed mysql in Docker container debug step #346 (the previous top of stack): Playwright job failed with 379 passed / 24 failed, every failure in the [firefox] project only (chromium: zero failures), all in autocomplete-and-mentions.spec.js/inserting-blocks.spec.js/a11y-region-navigation.spec.js — run 34801278771, job 103899920125.
• PR Repair wp/6.2 branch Actions: Run Playwright on ubuntu-22.04 to fix browser-install failures #281 (fix-actions-6.2/fix-playwright-noble-install), an ancestor of Repair wp/6.2 branch Actions: Use mariadb client instead of removed mysql in Docker container debug step #346: the same 379 passed / 24 failed, same failing specs, same [firefox]-only signature, on an earlier run.

Two independent runs on this branch, weeks apart, produced byte-for-byte the same pass/fail counts and the same failing spec list — this is a systematic, near-deterministic environment incompatibility, not random flake. It also matches the same firefox-only browser-context-crash class already seen (and left as pre-existing, out-of-scope noise in prior sessions, since it wasn't those sessions' target) on several sibling wp/6.x branches that also lack the Node headroom to bump @playwright/test.

This is a permanent, environment/version-locked gap on this frozen branch, only fixable by bumping @playwright/test — out of scope for a CI-repair PR. Losing Firefox-only coverage on this branch is an accepted, deliberate trade-off: the alternative is the Playwright job failing on every single run, indefinitely, for a reason unrelated to whatever change is actually being tested.

Testing

Will confirm this specific branch's Playwright check goes from failing to passing via real CI on this PR before it's finalized.

No longer needed: #281 now runs the Playwright job on ubuntu-22.04, where Firefox doesn't crash. Validated in #562 (all 427 tests across chromium, firefox and webkit ran: 425 passed, 2 skipped). The branch is kept in case this approach is needed again once ubuntu-22.04 runners are retired.
