FAQ
Do you develop custom Chrome extensions using Manifest V3?
Yes. I build custom Chrome extensions using Manifest V3, JavaScript, TypeScript and React.js. Features can include popup interfaces, settings, local storage, content scripts and background service workers, depending on your agreed scope.
Can you fix Chrome extension bugs or upgrade an existing browser extension?
Yes. I fix Chrome extension bugs, JavaScript errors, broken popups, API connections and service worker issues. Basic covers one agreed minor fix or UI update. Manifest V3 migration and larger extension upgrades are quoted after reviewing your source code.
Can you build browser automation and web scraping extensions?
Yes. I develop browser automation for form filling, repetitive page actions and workflow automation. Web scraping and data extraction features can export information to CSV, JSON or Google Sheets. Share your target website so I can confirm feasibility and scope.
Can you connect my Chrome extension to APIs, webhooks, CRMs or Google Sheets?
Yes. I provide REST API integration, webhook integration, CRM connections and Google Sheets integration. Standard includes one agreed feature OR one simple documented API endpoint. OAuth, databases and new backend development require a custom quote.
Can you build an AI Chrome extension using OpenAI or Gemini?
Yes. I can add OpenAI or Gemini API integration for summarization, content assistance and other agreed AI features. AI Chrome extensions are scoped separately. You provide the required API access and cover any third-party usage charges.
Can my browser extension work on Firefox and Microsoft Edge?
Firefox extension and Edge extension support are available by custom quote. I review your extension’s features, permissions and browser APIs before confirming compatibility. Additional browsers require separate testing and may affect pricing and delivery.
Will I receive source code and Chrome Web Store submission assistance?
Source code and installation guidance are included in every package. Chrome Web Store preparation and submission assistance are available as an extra through your developer account. Google controls approval and review timing, which sit outside development delivery.
