After you are done following the instructions to import Mellowtel in your extension that have been outlined in Quick Start you are ready to submit your extension to the web Store. This guide will help you submit your extension to the Chrome Web Store. Estimated time to complete: 3-5 minutes.

​
Web Store Justification

The Web Store requires you to justify the permissions you are requesting. Here is a template you can use (it explains how Mellowtel uses the permissions): DeclarativeNetRequest: 
The declarativeNetRequest permission is required to strip certain headers (e.g. X-Frame headers) from some responses on the sub_frame level. This allows displaying websites in an iframe without running into issues related to cross-origin resource sharing (CORS). These headers are immediately restored after the response is processed.
Host Permissions: 
The host permissions on all_urls are required to let declarativeNetRequest modify response headers on all URLs. This is necessary to strip certain headers (e.g. X-Frame headers) from some responses on the sub_frame level. This allows displaying websites in an iframe without running into issues related to cross-origin resource sharing (CORS). These headers are immediately restored after the response is processed.
Storage: 
The storage permissions is required to persist state specific to the extension and have a local logic to facilitate communications across the various parts of the extension.
