FAQ
Can you upgrade my extension from Manifest V2 or V1 to Manifest V3?
✅ Yes! I specialize in upgrading legacy extensions to Manifest V3, ensuring full compatibility with Chrome’s latest policies, background service worker migration, and permission model updates.
Will the extension work on Chrome, Firefox, and Microsoft Edge?
Absolutely. I build all extensions using the WebExtension API for cross-browser compatibility. I also test and adjust for each browser’s store requirements and quirks. In firefox case I have to completely make new extension
Can you help publish my extension on the Chrome Web Store or Mozilla Addons?
📝 Yes! I can assist with publishing, including generating proper ZIP packages, filling out store metadata, handling icons, and guiding you through the approval process.
Do you support advanced features like web scraping, automation, or API integration?
🧠 Of course! Whether it's scraping data from websites, automating browser tasks, or connecting to REST APIs, I can implement secure and scalable features based on your use case.
Can you provide a CRX file or bundled extension for manual installation?
Yes! I can deliver a signed .crx package along with the manifest and source files, perfect for manual installation or internal distribution without publishing on a store.
Can you build an extension that retrieves cookies or uses stored sessions?
🍪 Yes, I can create extensions that securely access cookies, session tokens, or other browser storage (like localStorage or indexedDB) — useful for automation or authenticated scraping. Note: Cookie access requires proper permissions and use-case compliance.
