Loved this blocker previously and always worked well. However since updating to the NG version it periodically loses all preferences I have set, and no longer blocks any pages. While I have a relatively short list of sites I want blocked, it is still rather annoying and were it to continue I would try find a better solution.
Thanks for the report. Please post bug reports on GitHub so I can gather more information and track down the cause of the issue. This may be the same issue as yours:
