Where to ask a question about Extension.dev, and where to report a bug.
Extension.dev is a platform for developing, previewing, and publishing browser extensions across browsers. It is built and run by one person, Cezar Augusto.
There is no ticket system here, and no response time worth promising you. Three channels carry the questions, and none of them asks you for an Extension.dev account.
The Extension Developers server is where questions and bug reports land. Start here when you are not sure where a problem belongs.
Extension.dev sponsors Extension.js, the open source framework it builds on, and that framework tracks its bugs in the open. File an issue there when the fault sits in the framework or its command line.
Write to the person who builds and runs the platform. Use this for billing, for a privacy or data request, or for anything you would rather not post in public.
The privacy notice and the terms live here too.
