What I Learned Publishing a Chrome Extension (FyreFighter)

Conclusion

When releasing the Chrome extension FyreFighter to the Chrome Web Store, the most decisive work happened before submitting the code: clarifying required permissions and publishing an explicit privacy disclosure. Web extensions requesting unfamiliar permissions trigger immediate suspicion; being able to concisely explain why every permission is strictly necessary directly determines review approval speed.

1. Minimal Manifest Permissions

Never request host permissions you do not actively use. Every additional privilege invites detailed compliance scrutiny from Google reviewers. I mapped every manifest entry directly to a specific user-facing feature.

2. Transparent Privacy Disclosures

While FyreFighter is a standalone product, support inquiries are unified under info@kimura512.dev. When user data interacts with LLM endpoints, articulating what data is sent—and critically, what data is never transmitted—fosters trust.

3. Unvarnished Store Assets

Store promotional screenshots must showcase real product UI without exaggerated mockups. Discrepancies between screenshots and actual extension behavior frequently cause review rejections.

4. Gradual Rollouts and Version Tags

Staged rollouts allow quick rollbacks if edge cases surface. I avoid arbitrary monthly update schedules, shipping new versions strictly for critical bug fixes or security enhancements.

5. Architectural Separation from Portfolio Site

The personal portfolio links out to the Chrome Web Store item. Advertising on kimura512.dev remains confined to blog articles, never polluting extension interfaces.

6. Constructive Review Management

When users express concern regarding permissions in public reviews, respond neutrally confirming that personal browsing data is never sold or retained.

7. Submission Package Integrity

Before uploading the distribution zip archive, increment the manifest version number and record changes in the release notes.

8. Landing Page Alignment

A dedicated landing page with a direct link to developer credentials in About establishes accountability for the Chrome Web Store team.

Summary

Align permissions, data flow explanations, and contact routes before initiating the store review process.

FAQ
