Manifest V3 Migration Services
BrowserGrids helps extension owners migrate older browser extensions to Manifest V3. Migration may affect background scripts, permissions, APIs, content scripts, storage, messaging, and extension behavior, so it should be handled carefully.
We review your current extension, identify required changes, rebuild affected architecture, test key workflows, and support store resubmission where needed.
What We Provide
We provide Manifest V3 audits, migration planning, service worker updates, permission review, API replacement, testing, and publishing support.
Migration Audit
We review the current manifest, scripts, permissions, APIs, background logic, and store risks.
Architecture Update
We update background logic, messaging, content scripts, storage, permissions, and related code paths.
Compatibility Testing
We test the migrated extension across target browsers and important user workflows.
Store Resubmission Support
We help prepare the updated extension package, listing notes, privacy details, and submission process.
The Challange
Manifest V3 migration can break important extension behavior if it is treated as a simple file update. Background behavior, permissions, and APIs may need meaningful changes. BrowserGrids handles migration as a structured technical project, not a quick patch.
