What is spam?
Upd: Any extension can't come back automatically in the browser without user interaction. We are limited by the Firefox browser, it's tech not possible, maybe the behavior you describe is related to a bug on the browser side, but we're not Firefox developers.
My extension has a Recommended badge with a deep review process for every version. The badge has only 100 extensions in the Firefox store. There is no reason to blame us and rate my hard work around the extension with 1-star without issues related to my extension.
