The official marketplace listing is the center of a browser extension launch because it carries installation, permission and review context. External launch platforms can add awareness, but they should send visitors to a clear listing that explains exactly what the extension changes in the browser.
Explain permissions plainly
Describe why each important browser permission is required and what data leaves the device. Keep the privacy policy, store listing and product website consistent. Trust friction can erase the benefit of additional launch traffic.
Demonstrate the browser workflow
Show the extension operating on a real page and make the before-and-after state visible. Avoid promotional images that hide the interface. Visitors should understand the value before they reach the install confirmation.
Sequence external promotion
Finish the marketplace listing and test installation first. Then use launch communities for feedback and product awareness. Add comparison or directory pages after positioning, screenshots and support information are stable enough to maintain.
