Planned for release to relay.firefox.com on February 3rd, 2026.

Switch to Turbopack

next.js 16 included changing the default bundler from Webpack to Turbopack. Turbopack uses a different naming scheme for classes, and our Playright End-to-End tests broke due to looking for the Webpack class names. This release includes adding data-testid attributes to rendered HTML, used by Playright tests. No visual or functional changes are expected in the frontend. PRs include:

• Switch from Webpack to Turbopack by @Vinnl in #6193
• Update e2e tests to use data-testid (MPP-4545) by @jwhitlock in #6209
• More changes for E2E tests (MPP-4545) by @jwhitlock in #6211
• fix(e2e): More E2E test updates to work against dev (MPP-4545) by @jwhitlock in #6231
• fix(e2e): Tips close button locator, playwright action fix (MPP-4545) by @jwhitlock in #6233
• fix(frontend): Load pending translations (MPP-4550) by @jwhitlock in #6235

Updates to /api/v1/terms-accepted-user

The /api/v1/terms-accepted-user is used by Firefox to add new Relay users. A cache key algorithm gave different answers for different servers, so there was no shared cache. Some runtime errors like timeouts were unhandled, giving generic 500 errors. This release includes a fixed cache key algorithm. It also handles the errors, but continues to return 500 Internal Server Error. Firefox should see no difference, and should continue to retry 500 responses. PRs include:

• fix(tests): More authentication test changes (MPP-3505) by @jwhitlock in #6196
• fix(tests): Update TermsAcceptedUserViewTest, reproduce bugs (MPP-3505, MPP-3928) by @jwhitlock in #6206
• Fix cache, catch exceptions in /api/v1/terms-accepted-user (MPP-3505, MPP-3928) by @jwhitlock in #6212
