Frequently Asked Questions
What’s the difference between MV2 and MV3—and will my extension still work?
MV3 replaces background pages with service workers and emphasizes declarativeNetRequest. We map your features to MV3-compatible patterns, refactor where needed, and test parity before rollout.
Can you publish to the Chrome Web Store for us?
Yes. We prepare listing assets, permissions and privacy disclosures, and handle reviewer questions until approval.
Do you build cross-browser extensions?
Yes—Chrome first, then Microsoft Edge Add-ons and Firefox AMO with minimal changes to UX and APIs.
Do you support automation or scraping?
We design compliance-first automation: rate limits, human-in-the-loop controls, audit logs, and consent. We do not support abusive use cases.
How do you keep extensions secure and fast?
Least-privilege permissions, strict CSP, code reviews, CI tests, error telemetry, and performance budgets.
Who owns the source code?
You do—ownership terms are defined in the contract. We can host repos in your org from day one.
What’s a typical timeline?
Discovery (3–5 days), Sprint build(s) (1–4+), Review & publish (3–10 days). Migrations start with a one-week audit.
Do you offer ongoing support?
Yes—retainers for maintenance, new features, monitoring, and policy changes.
