Frequently asked questions
Will the extension work in Firefox or Edge?▾
Edge is Chromium-based so most extensions work. Firefox requires WebExtensions API tweaks. Check the listing description for cross-browser support before assuming.
Does the listing include Chrome Web Store assets?▾
The better listings include icon sets at all required sizes, promotional images, and a privacy policy template. Submission still requires your own Google Developer account.
