Is Firefox Premium going to keep removing features people use, such as tab groups, and stopped nerfing add-ons by removing API for extensible functionality (such as proxy by url wildcard)? While a free product might be excused for doing this (because you get what you pay for), the expectations for paid product a bit higher. Now that I think about it, Firefox 56 updated with security patches in perpetuity and with active add-on ecosystem would be a great product. It was the most extensible browser ever, so new features can be delegated to add-on developers. Make the add-ons paid as well, I wouldn't mind.
