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.

The basic groups for organizing subscriptions are completely free, if you want extended features you should become a patron. The link on Patreon is available in the description with a list of features. It takes time to update the extension every time YouTube changes internally.
Furthermore, the decision to keep some features for the Patreon version of PocketTube was made to ensure the long-term feasibility of the free version.

That's great! So glad to hear you're enjoying PocketTube.

Thank you for sharing! We're waiting for the YouTube page to be completely loaded, and then we can start the extension sidebar. It can take time, but it's already optimized enough, and we make it as fast as possible.
